DC/DC Converter Controller Using a PICmicro …
2000 Microchip technology 1AN216 INTRODUCTIONIn many applications, a DC/DC Converter is used toproduce a regulated voltage or current, derived from anunregulated power supply, or from a battery. Examplesof these applications include battery chargers, elec-tronic air purifiers, emergency exit signs, and distrib-uted power some of those applications, a dedicated SwitchedMode Power Supply (SMPS) Controller IC is used inconjunction with a microcontroller. In other applica-tions, however, a dedicated SMPS Controller IC may beoverkill. An alternative approach is to generate a lowcost SMPS function in a smart microcontroller, such asthe PIC16C620A. This Application Note shows amethod of Using the microcontroller to perform simpleSMPS control circuits were built for evaluation. One circuit pro-vides a Constant Voltage output, the other a ConstantCurrent CONVERTERT here are several popular DC/DC Converter topolo-gies, such as the Boost and Fly-back Converter topolo-gies.
