SY8101B - Synchronous Step Down Regulator
The SY8101A, SY8101B, SY8101C and SY8101D are high efficiency 400kHz 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 wi
