Applications Note:AN_SY8101A/B/C/D High Efficiency 400kHz, 0.6A/1A/1.5A/2A, 16V Input Synchronous Step Down Regulator Preliminary Specification General Description 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 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.
