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.
