Power & Power Management



The iW600 secondary-side voltage position controller works with Renesas' iW1600 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 – all in a low cost, 2-lead DFN or 3-lead SOT-23 package.

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 and <30mW with the iW1601 PrimAccurate™ digital AC/DC controllers.

Works with the iW1600, iW1601 and iW1602 primary-side PWM controllers.
