General Description

The AP3301 EV1 board is a Quasi-Resonant

Flyback converter, operating under CCM and

DCM, the valley switching on mode function

will be appeared at all DCM region of variable

load & high input AC line voltage conditions,

it is employed with the peak-current control &

multi-mode PWM control functions. Based on

above the high performances are optimized &

achieved. It is designed to serve as an

example for High Efficiency, cost-effective &

components less consumer home appliance

systems. Its output power is rated at 42W with

12V-3.5A and peak power can be reach to 48W

at peak time. Its input power consumption is

less than 100mW at no load and meets DOE VI

and CoC Tier 2 energy efficiency requirement.

Key Features

 90 ~265VAC input range

 Multi-Mode PWM method operation & QR

valley switching cover full range of AC input at

heavy load, the switching frequency between

20Khz ~120Khz.

 With Valley Switching Turn on function that

improving power converting efficiency, the

90% Efficiency can be reached.

 During the burst mode operation the 100mW

low standby input power can be achieved.

 Dynamic response is improved during work at

three mode operation.

 Low start-up operating and low quiescent

currents at turn on moment.

 Soft start during startup process.

 Provide accurate constant voltage regulation &

accurate constant current (CC) regulation.

 Frequency fold back for high average

efficiency

 Built-in Jittering Frequency function is built in

to reduce EMI emission.

 Valley-on Soft Switching for Reducing EMI.

 Internal Auto Recovery OCP, OVP, OLP, OTP

Power Protection, cycle by cycle current limit,

also with DC polarity protection

 With a Brown out Protection.

Applications

 Switching AC-DC Adaptor & Charger

 Power home Appliances systems

 Set-top box & TV power supply

 Open frame switching power supply

Quick Start Guide

1. The evaluation board is preset at 12V/3.5A from output side of Block Terminal TH1 ~TH2

2. Ensure that the AC source is switched OFF or disconnected.

3. Connect the AC line wires of power supply to “L and N” on the AC side of Block Terminal.

4. Turn on the AC main switch.

5. Measure TH1~TH2 Block Terminal pins voltage to ensure correct output voltages at 12V
