NCV1362ACDR2G

The ON Semiconductor NCV1362ACDR2G is a highly integrated primary side quasi-resonant flyback controller designed for rugged and high-performance off-line power supplies. It achieves excellent line and load regulation for Constant Voltage and Constant Current applications without traditional secondary feedback circuitry.

This controller operates in valley lockout quasi-resonant peak current mode control at high loads for high efficiency, and automatically adjusts to pulse frequency modulation at lower loads with valley switching detection. Key features include AEC-Q100 qualification, ±5% Constant Voltage and Constant Current regulation, a wide VCC range up to 28V, and multiple protection features like over voltage, under voltage, and temperature shutdown.

The NCV1362ACDR2G is suitable for automotive auxiliary power supplies, on-board charger auxiliary power supplies, and traction inverter auxiliary power supplies. It comes in an 8-SOIC surface mount package.

Specifications include an operating voltage range of 6.5V to 28V and a frequency range of 1kHz to 140kHz. The operating temperature range is -40°C to 125°C (TJ). It features cycle-by-cycle peak current limit, secondary diode or winding short-circuit protection, and internal temperature shutdown.
