Dialog Semiconductor USA Pwm Controller, Sot-23-6; Input Voltage Dialog Semiconductor IW1602-10B

The iW1602 is a high-performance PWM controller designed for AC/DC power supply applications, utilizing digital control technology for peak current mode flyback power supplies. It operates in quasi-resonant mode, which enhances efficiency and reduces the need for external components, thereby simplifying EMI design and lowering overall material costs. The device features built-in protections, including output short-circuit, over-voltage, and over-current protections, along with user-configurable light-load operation modes to optimize performance based on application requirements. This controller supports a wide input voltage range and is optimized for compact applications, such as AC/DC adapters for media tablets and smartphones. It achieves low no-load power consumption, with values under 30mW at 230V AC when paired with a secondary-side controller, and maintains tight voltage and current regulation across varying loads. The iW1602 is packaged in a space-saving SOT-23 format, making it suitable for designs where board space is a concern.
