Renesas iW1702 | Demoboard iW1702-10B

Beschreibung

The iW1702 is a digital offline controller for AC/DC power supplies up to 45W optimized for 9V or greater output voltages. The part uses Renesas' PrimAccurate™ primary-side control technology, eliminating the need for an optical isolation device on the secondary, reducing component count and cost.For highest power density power supplies, the iW1702 can be paired with the iW676 digital synchronous rectifier controller, which drives a power MOSFET on the secondary side of the power supply to replace the main rectifying diode.
