SC4620: Low Input Voltage, High Efficiency, 2.5A Integrated FET Synchronous Step Down DC/DC Regulator | Semtech

The SC4620 is a highly integrated synchronous Step-down DC/DC Regulator designed for low input voltage range of 2.3V to 5.5 Volts. It CAN deliver 2.5A continuous output current with the output voltage as low as 0.5 Volts. The internal low R synchronous Power Switches eliminate DS(ON) the need for external Schottky Diode while delivering overall converter eficiency up to 95%. A power good pin is available to monitor the output voltage status. Operating frequency is adjustable from 200 kHz to 2MHz with a single resistor and it CAN be synchronized to an external Clock The SC4620 offers adjustable current limit, soft start and over temperature protection to safeguard the device under extreme operating conditions. The soft start provides a controlled output voltage ramp up at startup. When a Logic low is applied to the Enable pin, the SC4620 enters the shutdown mode and it consumes less than 1A of current.
