Function of DC-to-DC Converters

Before delving into the many types of DC-to-DC converters, it’s important to grasp their basic function. These devices take a defined DC input voltage and convert it to a different DC output voltage according on the system needs.

This conversion guarantees that all equipment performs at maximum efficiency by providing the necessary voltage. From production automation to renewable energy installations, DC-to-DC converters are the foundation of dependable industrial systems.

Improving Efficiency in Electronic Devices

Efficiency is an important consideration in the operation of electrical equipment, particularly in commercial and industrial settings. DC-to-DC converters optimize voltage conversion, lowering power loss and improving energy efficiency.

Efficiency is critical for battery-operated devices, such as warehouse robots. Efficient converters enhance battery life, reduce replacements, and promote environmental sustainability. Furthermore, they reduce the amount of heat produced during operation, lowering the need for sophisticated cooling systems and preserving energy.

High-efficiency converters also reduce operational costs, which extends the life of linked devices. Dorleco’s blog provides thorough information on power supply efficiency ratings.

Ensure voltage stability and control.

The sentence could not be directly located in the document. Could you confirm the exact phrasing or provide more context? DC-to-DC converters adjust output voltage to ensure that connected equipment operates within its ideal range. This stability protects delicate electronic components from being damaged by voltage fluctuations.

In businesses requiring precision, such as medical equipment and telecommunications, controlled and constant voltage is critical. Converters also help to control dynamic loads by modifying the voltage supply to match the changing demands of system components.

Types of DC-to-DC Converters:

1. Buck Converters: Utilizing Step-Down Capabilities

The buck converter is one of the most popular DC-to-DC converters because it can step down greater input voltages to lower output levels. These converters are appropriate for situations in which the power supply exceeds the load’s voltage needs.

Applications:

Automatic equipment

LED lighting systems.

Small motors in larger systems operate at greater voltages.

Key Advantages:

High efficiency with low heat generation.

Reduced operational costs.

Increased longevity for both the converter and the connected devices.

How It Works:

The core of a buck converter comprises a switch, a diode, and an inductor.

When the switch closes, energy is stored in the inductor.

This energy is released when the switch is opened, resulting in a voltage decrease.

The switch’s functioning determines the output voltage level.

2. Boost Converters: Stepping Up Voltage

Boost converters enhance the input voltage, making them necessary in situations where a greater output voltage is required. These are especially useful in energy harvesting applications like solar panels and battery-powered devices.

Applications:

Renewable energy systems.

Communication Devices

Remote sensors

Key Advantages:

Allows greater voltage levels for maximum performance.

Promotes energy-efficient power supply systems.

How It Works:

An inductor stores energy when the switch is closed.

When the switch opens, a diode transfers this energy to the output, increasing the voltage.

The period of the switch’s closure or opening impacts the voltage gain.

3. Buck-Boost Converters Offer Flexibility for Variable Voltage Sources

Buck-boost converters combine the functions of buck and boost converters, providing the ability to step up or down voltage as needed. Because of their versatility, they can be used in systems with diverse power sources.

Applications:

Portable electronics

Automotive systems

Devices using variable power sources

Key Advantages:

Versatility in a variety of applications.

seamless integration into complex systems.

Selecting the Right DC-to-DC Converter

The efficacy and efficiency of your electrical system are strongly dependent on choosing the right DC-to-DC converter. The type of power supply, load requirements, and application-specific needs are all important considerations.

4. Matching Applications and Converter Types:

Buck converters: Ideal for step-down voltage applications, such as powering LED lights or sensors in industrial environments.

Boost Converters : Ideal for applications requiring higher voltage, such as solar energy systems or remote sensors.

Buck-Boost Converters: Suitable for applications with variable power sources, they offer adaptability and stability.

Key Factors to Consider When Choosing a DC-to-DC Converter

Efficiency and heat dissipation:

High efficiency reduces energy loss and system heat.

Choose converters with effective heat dissipation, especially for small or high-temperature applications.

Input/output voltage and current requirements:

Identify the specific voltage and current requirements for your application.

Ensure that the converter satisfies these specifications.

Dimensions and Mounting restrictions:

Consider how much physical space is available for the converter.

Choose form factors that work perfectly with your system.

bq25185 + TPS61023 = USB or Solar lipoly with 5V output 🔋☀️🔌

We spent the weekend tweaking our bq25185

https://www.digikey.com/short/8hd2778w

designs and made one basic breakout for this flexible battery charging chip. Then, we made a board with a 3.3V buck output to charge the battery with a USB or solar panel and got a clean and consistent 3.3V out. With both of those working, here's a design for a version that has a 5V booster with the TPS61023

, which gives a nice clean 1A with a small bill of materials. Now you can use USB, DC, or solar to charge your favorite lipoly or liion chip and get 5V output. Maybe we'll make a version that can handle 3.6V LiFePO4 batteries, too? It's easy to set the bq to handle those by changing a single resistor.

TPS65131 split boost converter revision ✅🔧

We designed this split +12/-12 power supply board based on the TPS65131 (https://www.digikey.com/en/products/detail/texas-instruments/TPS65131RGER/1672464) a few months ago, but it languished while we worked on some other projects. We had an issue where the negative power rail was unstable. Thankfully, we found a thread that suggested slowing down the VNEG feedback loop (https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/628380/tps65131-q1-abnormal-operation-of-tps65131-q1-s-vneg) with a 51k resistor. We hand-soldered that in, and it worked nicely. Then, the other fix was to flip around the trimmers so the turn direction matched the expected behavior. This should be good to book a second prototype, and then it can go into the shop.

TPS65131 Split-Output Booster Supply

Generating a negative voltage over -5V is kinda annoying: most chargepumps max out at 5V inversion, and ones that can double-then-invert like the MAX232 aren't high current. We bumped into the TPS65131

https://www.digikey.com/en/products/detail/texas-instruments/TPS65131RGER/1672464

while working on our Floppsy design

- we need -12V to bias the Apple Disk ][ drive control system. It's a combo buck and boost: give it 3~5VDC and give you up to -15V and +15V output. The split supply part is particularly nice because you'll want +-12V or +-15V for analog projects. This standalone power supply breakout has two mini trim pots to help adjust the output voltages on both sides so you can have as little as +/-6V and up to +/-15V. With the 2A internal switches, you'll get a fair amount of current on either rail.

BQ25185 all-in-one Li-Poly board with 3.3V out 🔋🌞⚡

We had a previous version of this 3.3V buck output board with an MCP73831, but now we've replaced it with a BQ25185, which makes it a little more flexible: Vin can be up to 18V, and solar panels will work, too. There's also a power path and 4.5V regulated output. This charger chip can handle LiFePO4, but for that chip, we might swap the buck for a buck-boost or a boost / LDO to get the solid 3.3V output. Coming soon.
