UC3658 efficiency equivalent, high efficiency.
* Low RDS(ON) for internal switches (top/bottom) 100mΩ/70mΩ, 3A * 3~5.5V input voltage range * 1MHz switching frequency minimizes the external components * Internal soft.
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 w.
