ACT365
Product Brief, 15-Apr-11 The ACT365 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 ACT365 achieves excellent regulation and transient response, yet requires less than 150mW of standby power. The ACT365 is optimized for compact size 6W to 12W adapter applications. It is available in SOP-8 package. Figure 1: Simplified Application Circuit

GENERAL DESCRIPTION
The ACT365 belongs to the high performance patented ActivePSRTM Family of Universal-input AC/DC off-line controllers for adapter applications. It is designed for flyback topology working in discontinuous conduction mode (DCM). The ACT365 meets all of the global energy efficiency regulations (CEC, European Blue Angel, and US Energy Star standards) while using very few external components. The ACT365 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. Table 1: Output Power Table 85-265VAC TYPICAL APPLICATION

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. 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.
