LZC6100 - Critical Conduction Mode PFC Controller
The LZC6100 is an active power factor correction (PFC) controller with boost topology operates in quasi-resonant mode (QRM).
It uses voltage mode PWM control method that compares an internal sawtooth signal with output signal of the error amplifier to generate an external power MOSFET turn-off sign
LZC6100 Features
* Very fewer external components
* Zero-current detection (ZCD) without extra winding
* Internal total harmonic distortion (THD) optimizer
* Low operating current and power supply from HV pin directly without extra auxiliary winding
* Boost quasi-resonant conv
