High Efficiency 1.5MHz/1MHz, 1.5A/2A
Synchronous Step Down Regulator
General Description
The SY8009A and SY8009B are high-efficiency, high
frequency synchronous step-down DC-DC regulator
ICs capable of delivering up to 1.5A/2A output
currents. The SY8009 family operate over a wide input
voltage range from 3V to 5.5V 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 greater than
1MHz switching frequency.
