LZC6100 - LOZEN TECHNOLOGY

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 signal. LZC6100 introduce 500V start-up and novel power supply c.

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 converter controller for adaptors or high brightness LEDs
• Supports high power factor (PF>0.9) and low THD
• High precision constant voltage regulation for universal AC input (85VAC~265VAC)
• Various output voltage by input line voltage
• Maximum switching frequency limitation
• Lower standby power by burst operation
• Building in fast loop .
