The project published here is a synchronous step-down DC/DC converter based on the RT7258 chip. The chip has integrated high-side internal power MOSFET and gate driver for a low-side external power MOSFET. The board delivers 3.3V DC – 5A output current from 10V to 24V input supply. The RT7258‘s current mode architecture allows the transient […]

This is a multiple output power converter module that provides +/-10V (Dual 10V), 5V DC, and 3.3V DC from a 9V PP3 battery. This is a very useful project that has been designed for low-load current applications. Dual +/-10V output from a 9V battery is a key feature of the project. The battery holder can […]

This is a mini DC-DC converter with dual output from single 5V DC supply or USB power source (e.g., +/-18V from 5V/USB). The mini board will fit into small space and perform with high efficiency. Basically, the circuit transfers power from 5V/USB to the output side +/-18V with high isolation, without a direct connection between […]
