SY8104I Overview
The SY8104I is a high efficiency 500kHz synchronous step-down DC/DC regulator, which is capable of delivering up to 4A load current. It can operate over a wide input voltage range from 4.2V to 18V and integrate main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss. The SY8104I adopts the instant PWM architecture to achieve fast transient responses for high step down applications...
