SY81052 Overview
The SY81052 is a high efficiency, synchronous stepdown DC/DC converter capable of delivering 2A load current. The SY81052 operates over a wide input voltage range from 4.2V to 18V and integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss. The SY81052 adopts the instant PWM architecture to achieve fast transient responses for high step down applications and high...
