Application Notes
- DN-38 Unique "Cheap and Dirty" Converter for Low Power Bias SuppliesPDF, 65 Kb, File published: Sep 5, 1999
The UC495A PWM modulator provides a complete pulse-width modulation system in a single monolithic integrated circuit. Most-power supply designs use PWM controller ICs and MOSFET switches that require 10-15V bias supplies for proper operation. A common application problem is to first generate an auxiliary supply within this range. Although simple in many applications, developing this supply with a
