The SY26230 develops a high efficiency synchronous step-down DC/DC converter，which is capable of delivering 3A load current. The SY26230 operates over a wide input voltage range from 4.5V to 30V and integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.
The SY26230 adopts peak current control scheme. The switching frequency is adjustable from 500kHz to 2.5MHz using an external resistor. The device also features ultra low quiescent operating to achieve high efficiency under light load. The internal soft-start limits inrush current during power on.
The SY26230 is available in TSOT23-8 package.
