High Efficiency 400KHz, 3A,16V Input
Synchronous Step Down Regulator
Preliminary SPECIFICATION
General Description
The SY8133 is a high efficiency 400 KHz synchronous
step-down DC-DC converters capable of delivering 3A
output current. SY8133 operates over a wide input
voltage range from 4V to 15V and integrate main
switch and synchronous switch with very low Rds(on)
to minimize the conduction loss.
Low output voltage ripple and small external inductor
and capacitor sizes are achieved with 400KHz
switching frequency.
