Synchronous Rectifier Driver
The fundamental of SP6015 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 cross-
conduction at the same time. Specially, SP6015
is designed for LLC applications, and variable
switching frequency system .
The SP6015 is a dual fast turn-off intelligent
controller to drive two N-CH power MOSFETs
in LLC resonant converters for synchronous
Storage area network power supplies
