UC3875L Overview
The UTC UC3875L is a high performance current mode PWM controller ideally suited for low standby power. The PWM switching frequency is programmable externally at normal operation. Low VDD startup current make the power reliable on startup design and a large value resistor could be used in the startup circuit to minimize the standby power.
