ISO5125I-65 is a highly integrated, full-featured PWM controller for high-efficiency isolated flyback power supplies. It is designed for use in applications such as smart appliances, industrial power supplies, LED drivers, and USB PD chargers.
Key features of ISO5125I-65 include an integrated 650 V MOSFET with fast turn-on and turn-off speeds, primary-side regulation for accurate output voltage regulation without requiring an optocoupler, an integrated 65 kHz jittered fixed-frequency operation for improved EMI performance, and a wide input voltage range of 30 V to 550 V for use in universal input voltage applications.
The device also includes comprehensive protection features such as over-temperature protection, output short-circuit protection, output over-voltage protection, and line over-voltage protection for robust and reliable operation. With a compact SO-8 package and minimal external components required, ISO5125I-65 offers a simple and cost-effective solution for designing high-efficiency isolated power supplies
