UC3658 Datasheet (UTC) - HIGH EFFICIENCY

UC3658, HIGH EFFICIENCY

The UTC UC3658 is a high-efficiency 1MHz synchronous step-down DC-DC regulator IC capable of delivering up to 3A output current.

The UTC UC3658 operates over a wide input voltage ranging form 3~5.5V and integrate main switch and synchronous switch with very low RDS(ON) to minimize the conduction lo

* 3~5.5V input voltage range

* 1MHz switching frequency minimizes the external components

* Internal softstart limits the inrush current

* 100% dropout operation
