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 NCP4305 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 NCP4305 features a very precise 0 mV turn-off comparator that
supports even very low current flowing through the MOSFET even
when very low R synchronous MOSFETs is used.
