HIGH PERFORMANCE POWER FACTOR CORRECTOR AP1662

Jul. 2012 Rev. 1. 3 BCD Semiconductor Manufacturing Limited

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.
