A Simple Circuit for Driving Microcontroller Friendly PWM Generators
The recent interest in intelligent power supplies has
driven the development of a new class of microcontroller
friendly PWM generators. These PWM generators
are the mixed signal control blocks for switch mode
power supplies. One such device is the MCP1630. The
MCP1630 contains the 3 main elements for designing
a switching power supply as a peripheral to a microcontroller: a set/reset flip-flop, a high-speed voltage comparator and an op amp to implement the error amplifier. This technical brief examines a design that combines the PIC10F206, a 6-pin SOT-23 microcontroller, with the MCP1630.
