TNY277PN is a type of IC this IC has 7 pin its a tiny switch IC in which one pin is not present its trough hole components. It has manufactured by Power integration. Tiny Switch-III combines a high-voltage power MOSFET switch with a power supply controller in one device. Unlike conventional PWM (pulse width modulator) controllers, it uses a simple ON/OFF control to regulate the output voltage. The controller consists of an oscillator, enable circuit (sense and logic), current limit state machine, 5.85 V regulator, BYPASS/ MULTI-FUNCTION pin under voltage, overvoltage circuit, and current limit selection circuitry, over-temperature protection, current limit circuit, leading edge blanking, and a 700 V power MOSFET. Tiny Switch-III incorporates additional circuitry for line under voltage sense, auto-restart, adaptive switching cycle on-time extension, and frequency jitter.
