The project presented here is a compact, high-efficiency, low-cost, and low-EMI step-up DC/DC module designed to replace LDO regulators. This small module not only saves on solution size and cost but also eliminates the need for a heatsink, occupying the same space as a TO-220 package...

This 350W power factor boost converter is designed for inverter-fed BLDC/PMSM motor appliances, A/C units, Refrigerators, and industrial power supplies. The circuit is a continuous-conduction-mode boost converter implemented using a UCC28180 PFC controller module which provides all...

This is a low-cost boost converter that converts a 3.3V input to 5V at 250mA load current. The LM2578A chip is used to build this project. The LM2578A is a switching regulator which can easily be set up for such DC-to-DC voltage conversion circuits as the buck, boost and inverting...

The project shown here is a boost converter that provides 9V DC output from 2.1V to 5.5V input. It is a good choice for battery-operated devices where the converter can be connected to 2x 1.5V, 3 x 1.5V Battery, 1 x Li-ion, 2 x NICAD, 2 x NIMH, and provide 9V Output. The board is...

The project presented here is a boost converter with 24V output from 4.5V to 20V DC Input. The project is built using an LT8357 chip and configured as a boost converter. Under voltage lockout, and soft-start are a few key features of the project. LED D1 indicates the output, and screw...

The project presented here is capable of supplying 400mA of current from a 3.7V Li-Ion/Li-Po Battery input with a 5V output. The converter has an internal soft start and internal frequency compensation features. The project is built using LTC3426 SOT23-6 chip. The LTC3426 chip is in a...

The project presented here is a powerful constant-frequency, pulse-width modulating (PWM), current-mode step-up DC-DC switching regulator efficiently producing 5V from input voltages between 3V to 5V. The project can be used in a portable device that works with a battery. The module...

The circuit presented here is a 300W off-line power factor correction (PFC) boost converter providing a nominal regulated output voltage of 375V @ 0.8A of load current. The project accommodates an input voltage range of 85V AC to 265VAC and uses average current mode control at a fixed...
