AP3983B/C/D

HIGH FREQUENCY PRIMARY SIDE POWER SWITCHER FOR OFF-LINE SMPS

Description

Pin Assignments

The AP3983B/C/D are series of high frequency power switcher for

power supplies with better conversion efficiency, better voltage &

current accuracy, and improved protection functions. Typical

applications include charger, adapter for ADSL, home appliance

power supply, LED lighting power supply and PC auxiliary power

supplies. The AP3983B/C/D with built in MOSFET, regulates the

output voltage and current in the primary side by piece-wise Pulse

Frequency Modulation (p-PFM) in discontinuous conduction mode

(DCM). The system operating frequency reduces linearly from heavy

load to light load in each interval of the p-PFM, and enters constant

current mode when the load current equals to the maximum system

output current.

(Top View)

The AP3983B/C/D has good transient characteristics. Typically,

minimal voltage of 4.3V at PCB side can be achieved for dynamic test

of 5V application system.

The AP3983B/C/D provides operating frequency dithering function to

improve EMC performance of power supply. The AP3983B/C/D also

has built-in fixed cable voltage drop compensation and adjustable line

voltage compensation.

The AP3983B/C/D solution has fewer component number, smaller

size, and lower total cost.

VCC

The AP3983B/C is packaged in SO-7. The AP3983C/D is packaged in

PDIP-7.
