SY8101A
Description
The SY8101A, SY8101B, SY8101C and SY8101D are high efficiency 400k Hz synchronous step-down DCDC converters capable of delivering 0.6A, 1A, 1.5A, 2A output currents, respectively. SY8101A/B/C/D operate 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 400k Hz switching frequency.
