POWER FACTOR CORRECTOR
VERY PRECISE ADJUSTABLE INTERNAL OUTPUT OVERVOLTAGE PROTECTION HYSTERETIC START-UP (ISTART-UP < 0.5mA) VERY LOW QUIESCENT CURRENT (< 3.5mA) INTERNAL START-UP TIMER TRANSITION MODE OPERATING TOTEM POLE OUTPUT CURRENT: ±400mA DIP8/SO8 PACKAGES
DESCRIPTION The L6560/A is a monolithic integrated circuit in Minidip and SO8 packages, designed as a controller and driver of a discrete power MOS
transistor for the implementation of active power factor correction, for sinusoidal line current consumption.
Realized in mixed BCD technology, the chip integrates:
- An undervoltage lockout with micropower startup and hysteresis.
- An internal temperature compensated precise band gap reference.
- A stable error amplifier.
