Overview

NCP1336A/B Quasi-Resonant Current Mode Controller for High Power Universal Off-Line Supplies The NCP1336 hosts a high−performance circuitry aimed to www.onsemi.com powering quasi−resonant converters.

Capitalizing on a novel QUASI−RESONANT PWM valley−lockout system, the controller shifts gears and reduces the CONTROLLER FOR HIGH POWER switching frequency as the power loading becomes lighter.

This AC−DC WALL ADAPTERS results in a stable operation despite switching events always occurring in the drain−source valley.

Key Features

two latch inputs: one dedicated to Over Temperature protection (OTP) which offers an easy means to connect a pull.
down temperature sensor like an NTC, and a second one more classical that can be used to perform an accurate Over Voltage Protection. Finally, a brownout pin which stops the circuit operation in presence of a low mains condition is included. PIN.
