AP8010

AiT Semiconductor Inc. www.ait-ic.com AP8010 AC-DC PWM CONTROLLER PRIMARY SWITCHING REGULATORS DESCRIPTION The AP8010 is a high performance AC-DC off‐line controller for low power battery charger and adapter applications with Universal‐input. It uses Pulse Frequency and Width Modulation (PFWM) method to build discontinuous conduction mode (DCM) flyback power supplies. The AP8010 utilizes primary‐side sensing and regulation technology to provide accurate constant voltage, constant current (CV/CC) regulation without requiring an opto‐coupler and secondary control circuitry. It also eliminates the need of external loop compensation circuitry while maintaining stability. The AP8010 achieves excellent regulation and high average efficiency, yet meets the requirement for standby power less than 150mW. The AP8010 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, VDD over voltage, feedback open and short, and over temperature conditions. Integrated line and primary inductance compensation circuitry, the AP8010 provides accurate constant current operation despite wide variations in line voltage and primary inductance. It has the built‐in cable voltage drop compensation function. The AP8010 is available in SOT-25 package.
