SP6051 Overview
The fundamental of SP6051 synchronous rectifier (SR) driver IC is based on our U.S. patented methods that utilize the principle of “prediction” logic circuit. The IC deliberates previous cycle timing to linear control the SR in present cycle by “predictive” algorithm that makes adjustments to the turn-off time, in order to achieve maximum efficiency and avoid crossconduction at the same time.
SP6051 Key Features
- Offers efficiency improvement over Schottky
- Low Standby Power to meet DOE Lot 6
