iW671 に関するリソース
説明
The iW671 secondary-side synchronous rectifier controller complements several of Renesas' primary-side controllers to deliver the high efficiency needed for high-power density power supplies and power adapters. The iW671 uses proprietary digital adaptive turn-off control technology to replace the secondary-side Schottky diode with a MOSFET for high-power density power supplies. While conventional synchronous rectifier designs require the use of a Schottky diode in parallel with the synchronous rectifier to maintain efficiency, an inherently higher cost approach, the adaptive control in the iW671 minimizes dead time and eliminates this need. More efficient than the diodes it replaces, the iW671 is also more efficient than conventional synchronous rectifiers.
With an integrated adaptive voltage monitor function, the iW671 works with the iW1766C1 primary-side PWM controller to enable the high power density needed for small form factor power supplies with lower output ripple, ultra-low standby power, and ultra-fast Dynamic Load Response (DLR).
