SY8113 High Efficiency, 500kHz, 3A, 16V Input Synchronous Step Down Regulator General Description The SY8113 is a high efficiency 500 kHz synchronous step-down DC-DC converter capable of delivering 3A current. The SY8113 operates over a wide input voltage range from 4.5V to 16V and integrates 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 500 kHz switching frequency. It adopts the instant PWM architecture to achieve fast transient responses for high step down applications Ordering Information SY8113 ( ) Temperature Code Package Code Optional Spec Code Temperature Range: -40°C to 85°C Ordering Number Package type Note SY8113ADC TSOT23-6 -- Featur [ ... ]
