Power Projects
Stepdown DC-DC Converter with Current Limit
The step-down DC-DC Converter project presented here provides 3.3V @ 1A output from an input range of 8V to 36V DC.
Step Up DC-DC Converter – 24V/10mA Output from 12V DC Input – Compatible to TO220 LDO
The project demonstrated here is a small-size solution, high-efficiency, low-cost, and low-EMI step-up DC/DC module for LDO regulator replacement.
Deep Discharge Protector for 3.6V Li-Ion Battery
A rechargeable battery’s load should be disconnected at the point of complete discharge, to avoid a further (deep) discharge that can shorten its life or destroy it.
Breakout Board for ATX Power Supply – Benchtop Power Supply
This ATX Power supply breakout board enables users to use an ATX power unit as a benchtop power supply.
Li-Ion/Li-Po 18650 Battery to 5V Boost Converter
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.
1200V High-Current Half-Bridge using FAN73912
The project presented here is designed for high-voltage and high-speed driving for MOSFETS and IGBTs that operate up to +1200V.
High Current Half-Bridge with Over Current & Voltage Feedback for Step Down DC-DC Converter
This project enables the user to create a high current DC-DC converter.
3V to 5V DC Output Step-Up DC-DC Converter using MAX668
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.
DC-HV DC Converter – 200V @ 20mA Output with 12V DC Input
This is a low-cost DC-HV DC converter built using TL3843 Low-Power Current-Mode PWM Controller from TI.
