The iW1699 is a high-performance AC/DC controller designed to drive an external power N-channel MOSFET for peak current mode PWM flyback power supplies. It uses Renesas' PrimAccurate™ primary-side control technology, eliminating the need for a secondary-side regulator and optocoupler, reducing component count and solution cost while easily meeting the US DoE’s external power supply efficiency standard and the EU’s Code of Conduct, Version 5, Tier 2 external power supply standard, with no-load power consumption less than 30mW.
It integrates a constant current mode on some options so it can be used in adapter applications, with a constant current accuracy >3%. 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 over-temperature.
For lower output ripple, see the iW1699B 30W AC/DC off-line controller page.
