ACT336

Product Brief, 15-Apr-11

High Performance ActivePSR^TMPrimary Switching Regulator

over temperature conditions.

The ACT336 ActivePSR^TMis optimized for high

FEATURES

• Ultra Low Standby Power < 30mW

performance, cost-sensitive applications, and

utilizes Active-Semi’s proprietary primary-side

feedback architecture to provide accurate constant

voltage, constant current (CV/CC) regulation

without the need of an opto-coupler or reference

device. Integrated line and primary inductance

compensation circuitry provides accurate constant

current operation despite wide variations in line

voltage and primary inductance. Integrated output

cord resistance compensation further enhances

output accuracy. The ACT336 achieves excellent

regulation and transient response, yet requires less

than 30mW of standby power.

• Patented Primary Side Regulation

Technology

• Suitable Operation Frequency up to 85kHZ

• Proprietary Fast Startup Circuit

• Integrated Line and Primary Inductance

Compensation

• Integrated Programmable Output Cord

Resistance Compensation

• Line Under-Voltage, Output Over-Voltage,

Output Short-Circuit and Over-Temperature

Protection

The ACT336 is optimized for compact size 2W to

6.3W charger applications. It is available in space-

saving 8 pin SOP-8 package.

• Complies with all Global Energy Efficiency

and CEC Average Efficiency Standards

• Adjustable Power from 2W to 6.3W

• Minimum External Components

• SOP-8 Package

Simplified Application Circuit

APPLICATIONS

• Chargers for Cell Phones, PDAs, MP3,

Portable Media Players, DSCs, and Other

Portable Devices and Appliances

• RCC Adapter Replacements

• Linear Adapter Replacements

• Standby and Auxiliary Supplies

GENERAL DESCRIPTION

The ACT336 belongs to the high performance

patented ActivePSR^TMFamily of Universal-input

AC/DC off-line controllers for battery charger and

adapter applications. It is designed for flyback

topology working in discontinuous conduction mode

(DCM). The ACT336 meets all of the global energy

efficiency regulations (CEC, European Blue Angel,

and US Energy Star standards) while using very

few external components.

The ACT336 ensures safe operation with complete

protection against all fault conditions. Built-in

protection circuitry is provided for output short-

circuit, output over-voltage, line under-voltage, and

Innovative Power^TM
