AP3988/89/90

PRIMARY SIDE POWER SWITCHER FOR OFF-LINE SMPS

Description

Pin Assignments

The AP3988/89/90 is a performance enhanced 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 controller 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.

SO-7 (M Package) For AP3988

(Top View)

The AP3988/89/90 provides operating frequency dithering function

to improve EMC performance of power supply. The AP3988/89/90

also has built-in fixed cable voltage drop compensation (5% of

nominal system output voltage) and adjustable line voltage

compensation.
