ACT361

Product Brief, 15-Apr-11

High Performance ActivePSR^TMPrimary Switching Regulator

The ACT361 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

over temperature conditions.

FEATURES

• Patented Primary Side Regulation

Technology

• No Opto-Coupler

The ACT361 ActivePSR^TMis optimized for high

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 ACT361 achieves excellent

regulation and transient response, yet requires less

than 150mW of standby power.

• Best-in-Class Constant Voltage, Constant

Current Accuracy

• Low EMI

• Proprietary Fast Startup Circuit

• Built-in Soft-Start 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 ACT361 is optimized for 2W to 7W

applications. It is available in space-saving 6 pin

SOT23-6 package.

• Complies with all Global Energy Efficiency

and CEC Average Efficiency Standards

• Adjustable power from 2W to 7W

• Minimum External Components

• Tiny SOT23-6 Package

GENERAL DESCRIPTION

ACT361

The ACT361 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 ACT361 meets all of the global energy

efficiency regulations (CEC, European Blue Angel,

and US Energy Star standards) while using very

few external components.
