2A Synchronous Step Down Regulator Preliminary Spec General Description The SY8008A, SY8008B and SY8008C are highefficiency 1.
5MHz synchronous step-down DC-DC regulator ICs capable of delivering up to 1.
2A output currents.
The SY8008 family operate over a wide input voltage range from 2.
5V 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 1.
5MHz switching frequency.
This along with small SOT23/TSOT-23 footprint provides small PCB area application.
