Product Brief

PRIMARY SIDE CONTROL IC FOR OFF-LINE BATTERY CHARGERS

AP3706

Description

Parametric Table

The AP3706 is a high performance AC/DC power supply

controller for battery charger and adapter applications.

The device uses Pulse Frequency Modulation (PFM)

method to build discontinuous conduction mode (DCM)

flyback power supplies.

Startup Current (µA)(Typ)

UVLO Threshold on/off (V) (Typ)

Operating Current (µA) (Typ)

Standby Power (W)

18.5/7.4

680

<0.3

The AP3706 provides constant voltage, constant current

(CV/CC) regulation without requiring an opto-coupler

and secondary control circuitry. It also eliminates the need

of loop compensation circuitry while maintaining stabil-

ity.

Package

SOIC-8

Applications

The AP3706 achieves excellent regulation and high power

efficiency, the no-load power consumption is less than

200mW at 265VAC input.

Adapters/Chargers for Cell/Cordless Phones, PDAs,

MP3 and Other Portable Apparatus

Standby and Auxiliary Power Supplies
