DN-29 UC3842A Family - Frequency Foldback Technique Provides Protection
PDF, 51 Kb, File published: Sep 5, 1999
Excessive power dissipation can occur in switch-mode power supplies during startup and overload conditions. Many sophisticated PWM controllers provide the means for protection against these problems; however simple low-cost controllers require additional circuitry. This design note describes a circuit that uses only one additional resistor and transistor to enhance the performance of the UC3842A
