HIGH PERFORMANCE POWER FACTOR CORRECTOR
General Description
Features
AP1661A
The AP1661A is an active power factor control IC
which is designed mainly for use as pre-converter in
electronic ballast, AC-DC adapters and off-line SMPS
applications.
The AP1661A 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 opera-
tion. 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
AP1661A features low start-up current, low operation
current and low power dissipation. The AP1661A also
has rich protection features including over-voltage pro-
tection, input under-voltage lockout with hysteresis
and multiplier output clamp to limit maximum peak
current.
The AP1661A meets IEC61000-3-2 standard even at
one-quadrant load and its THD is lower than 10% at
high-end line voltage and full load.
· Comply with IEC61000-3-2 Standard
· Proprietary Design for Minimum THD
· Zero Current Detection Control for DCM Bound-
ary Conduction Mode
· Adjustable Output Voltage with Precise Over-
Voltage Protection
· Ultra-low Startup Current: 30µA Typical
· Low Quiescent Current: 2.5mA Typical
· Precision Internal Reference Voltage: 1%
· Internal Startup Timer
· Disable Function for Reduced Current
Consumption
· Totem Pole Output with 600mA Source Current
and 800mA Sink Current Capability
· Under-voltage Lockout with 2.5V of Hysteresis
Applications
· AC-DC Adapter
· Off-line SMPS
· Electronic Ballast
This IC is available in SOIC-8 and DIP-8 packages.
