iW628 Functional Block Diagram
Description
The iW628 is a precision voltage reference used to quickly detect voltage drops on the output of an AC/DC power supply and provide instantaneous feedback to the controller in order to improve the dynamic loop response of the overall power supply.
The device consumes a minimum amount of current, allowing the overall power supply to maintain no-load power consumption levels below 20mW. As a complement to Renesas' family of PrimAccurate™ AC/DC controllers, the iW628 helps improve the already high-performing AC/DC controllers while eliminating additional secondary-side components normally required to achieve similar levels of performance.
Applications
- AC/DC Power Adapters
- AC/DC Networking and Embedded Applications
- Precision Voltage Reference
