SP6002

Synchronous Rectifier Driver

DESCRIPTION

The fundamental of SP6002 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 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. It also

maintains the MOSFET’s body diode conduction

at minimum level. The SP6002 is capable to

adapt in almost all existing forward converters

with few adjustments considered necessary.

FEATURES

•

Offers 4 to 8% efficiency improvement over

Schottky Diodes (depend on drive

configuration of the SR).

•

Drives all logic level Power MOSFET.

Prediction gate timing control.

Minimum MOSFET body diode conduction.

Operating frequency up to 650 KHz.

Synchronize to transformer

voltage waveform.
