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. The project consists of a high current inductor, high current low voltage 2 x MOSFETs, half-bridge driver LT1158 chip, voltage feedback using onboard R9 and R10 resistor dividers, shunt resistor for overcurrent shut-down. The project has all the required components to create a high current step-down DC-DC converter, refer to the datasheet of LT1158 chip for components selection. The Half-bridge requires a PWM input signal, Arduino or another microcontroller/DSP can be used as a host to generate PWM signal and control enable and fault conditions.
