SM8103E Overview
The SM8103E is a high efficiency, 500kHz synchronous step-down DC/DC regulator capable of delivering up to 3A load current. It can operate over a wide input voltage range from 4.5V to 18V and integrate main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss. The SM8103E adopts the instant PWM architecture to achieve fast transient responses for high step down applications.
