® ACT336 Product Brief, 15-Apr-11 over temperature conditions. The ACT336 ActivePSRTM is 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 ACT336 achieves excellent regulation and transient response, yet requires less than 30mW of standby power. The ACT336 is optimized for compact size 2W to 6.3W charger applications. It is available in spacesaving 8 pin SOP-8 package. Figure 1: Simplified Application Circuit High Performance ActivePSRTM Primary Switching Regulator FEATURES • Ultra Low Standby Power < 30mW • 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 • Complies with all Global Energy Efficiency and CEC Average Efficiency Standards • Adjustable Power from 2W to 6.3W • Minimum External Components • SOP-8 Package 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 ActivePSRTM Family 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 shortcircuit, output over-voltage, line under-voltage, and Innovative PowerTM ActivePSRTM is a trademark of Active-Semi. -1- www.active-semi.com Copyright © 2011 Active-Semi, Inc. ® Product Brief, 15-Apr-11 ACT336 TOP MARK ACT336SH ORDERING INFORMATION PART NUMBER ACT336SH-T TEMPERATURE RANGE -40°C to 85°C PACKAGE SOP-8 PINS 8 PACKING METHOD TAPE & REEL PIN CONFIGURATION SOP-8 ACT336SH ACT336SH PIN DESCRIPTIONS PIN SOP-8 1 2,4,7 8 6 5 3 NAME SW G BD VDD FB CS DESCRIPTION Switch Drive. Switch node for the external NPN transistor. Connect this pin to the external power NPN’s emitter. This pin also supplies current to VDD during startup. Ground(2,4 and 7 pin must be connected together). Base Drive. Base driver for the external NPN transistor. Power Supply. This pin provides bias power for the IC during startup and steady state operation. Feedback Pin. Connect this pin to a resistor divider network from the auxiliary winding. Current Sense Pin. Connect an external resistor (RCS) between this pin and ground to set peak current limit for the primary switch. The peak current limit is set by (0.396V × 0.9) / RCS.
