The iW600 secondary-side voltage position controller works with Renesas' iW1600-03 and iW1601 primary-side PWM controllers to enable travel adapters with very low no-load standby power and fast dynamic load response. The iW600 works on the secondary side to detect dynamic load changes on the output and uses Renesas' patented technology to send a wake-up signal to the input via the main flyback transformer, eliminating the need for an optocoupler, reducing cost and improving reliability. Working normally in an off-state with negligible current draw, the iW600 enables 10W travel adapters with no-load power consumption of <10mW when used with Renesas' iW1600-03 and <30mW with the iW1601 PrimAccurate™ digital AC/DC controllers. Works with the iW1600-03, iW1601 and iW1602 primary-side PWM controllers.
