SQ20953
SQ20953 is Synchronous Step Down Regulator manufactured by Silergy.
High Efficiency Fast Response, 3A, 30V Input Synchronous Step Down Regulator
General Description
The SQ20953 develops a high efficiency synchronous step-down DC/DC converter ， which is capable of delivering 3A load current. The SQ20953 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 SQ20953 adopts peak current control scheme. The switching frequency is adjustable from 500k Hz 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 SQ20953 is available in TSOT23-8 package.
