DESCRIPTION
The L6560/A is a monolithic integrated circuit in
Minidip and SO8 packages, designed as a con-
troller and driver of a discrete power MOS transis-
tor for the implementation of active power factor
correction, for sinusoidal line current consump-
tion.
Realized in mixed BCD technology, the chip inte-
grates:
- An undervoltage lockout with micropower start-
up and hysteresis.
- An internal temperature compensated precise
band gap reference.
- A stable error amplifier.

- One quadrant multiplier.
- Current sense comparator.
- An output overvoltage protection circuit.
- A totem-pole output stage able to drive a
POWER MOS or IGBT devices with source
and sink current of 400mA. The chip works in
transition mode and is particularly intended
for lamp ballast applications and for low
power SMPS.
