Preliminary Datasheet
HIGH PERFORMANCE POWER FACTOR CORRECTOR
General Description
The AP1662 is an active power factor control IC
which is designed mainly for use as a pre-converter
in electronic ballast, AC-DC adapter and off-line
SMPS applications.
.
The IC includes an internal start-up timer for
stand-alone applications, a one-quadrant multiplier to
realize near unity power factor and a zero current
detector to ensure DCM boundary conduction
operation.
The totem pole output stage is capable of driving
power MOSFET with 600mA source current and
800mA sink current.
Designed with advanced BiCMOS process, the
AP1662 features low start-up current, low operation
current and low power dissipation. The AP1662 also
has rich protection features including over-voltage
protection, input under-voltage lockout with
hysteresis and multiplier output clamp to limit
maximum peak current.
The AP1662 meets IEC61000-3-2 standard even at
one-quadrant load and THD lower than 10% at
high-end line voltage and full load.
The IC is available in SOIC-8 and DIP-8 packages.
