NCP4306 Synchronous
Rectification
Evaluation
Board User'sManual
Description
This evaluation board user’s manual describes a high efficiency
synchronous rectification evaluation board that can easily replace a
secondary side rectification diode in an SMPS.
The NCP4306 is used as synchronous rectification controller. The
evaluation board has very few external components and illustrates
how small and effective such a design can be.
The NCP4306 features a very precise 0 mV turn
−
off comparator
that supports even very low current flowing through the MOSFET
even when very low RDSON synchronous MOSFETs is used.
NCP4306 can be used in application working in CCM without
external synchronization thanks to very low propagation delay and
strong driver.
