LZC6100 Description
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 pares 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 circuit (patent pending) for VCC without extra axillary winding.
LZC6100 Key Features
- Very fewer external ponents
- Zero-current detection (ZCD) without extra
- Internal total harmonic distortion (THD)
- Low operating current and power supply
- 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
