The iW1762 is a high-performance AC/DC controller designed to drive an external power N-channel MOSFET for peak current mode PWM flyback power supplies. Optimized for power supplies with output power between 15W to 24W, the iW1762 is ideal for power adapters in networking equipment and monitors.

The iW1762 easily meets the US DoE’s external power supply standard and the EU’s Code of Conduct, Version 5, Tier 2 standard, with no-load power consumption less than 20mW while complying with active mode efficiency requirements. As a PrimAccurate™ controller, the iW1762 does not need any direct secondary-side feedback components, eliminating the need for optocouplers, and reducing component count and solution cost. Additional features include Renesas' proprietary EZ-EMI™ technology, adaptive multi-mode PWM/PFM control for optimal efficiency across all loads, five selectable cable and connector voltage drop compensation voltages, and robust operation with full protection from overvoltage and overtemperature.
