The SY26335 develops a high efficiency synchronous step-down DC/DC converter capable of delivering 3.5A load current. The SY26335 operates over a wide input voltage range from 4.2V to 40V and integrates main switch and synchronous switch with very low R_DS(ON) to minimize the conduction loss.

The SY26335 adopts peak current control scheme. The switching frequency is adjustable from 300kHz to 2.2MHz using an external resistor. The device also features ultra low quiescent operating to achieve high efficiency under light load. And the internal soft-start limits inrush current during power on.
