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 operatio
NCP1336A 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 circ
