This is a digital SMPS that I designed with current sensing capablitlies. It is powered from a PIC18F13K22, but any PIC will work that has the same pinout. The PIC runs at 64Mhz to output a 250Khz signal used in half bridge mode. Input: 15V Max Output: Not tested, but 0 to 15V Iout(max):Not tested, 2A
Has spare outputs for Red,Green,and Blue LEDs. UART/I2C Connectors for board to board communications PIC16F series with 16Bit PWM should work as well.
Note: Current schematic (9/4/2018) has PGC and PGD reversed on the programming side. Just reverse the connections with a wire and it will work.
