ACT366

Active-Semi FEATURES • Patented Primary Side Regulation Technology ACT366 Product Brief, 15-Apr-11 The ACT366 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 ACT366 achieves excellent regulation and transient response, yet requires less than 150mW of standby power. The ACT366 is optimized for compact size 6W to 14W adapter applications. It is available in SOP8/EP (Exposed Pad) package.

It is designed for flyback topology working in discontinuous conduction mode (DCM). The ACT366 meets all of the global energy efficiency regulations (CEC, European Blue Angel, and US Energy Star standards) while using very few external components. The ACT366 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 over temperature conditions.

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. 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. For more detailed information, see Application Information. Exposed Pad shown as dashed box. The exposed thermal pad should be connected to board ground plane and pin 4. The ground plane should include a large exposed copper pad under the package for thermal dissipation (see package outline). The leads and exposed pad should be flush with the board, without offset from the board surface.
