Description
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 RDS(ON) synchronous power switches eliminate the need for external Schottky diode while delivering overall converter effciency up to 95%.

Features
◆ VIN Range: 2.3 – 5.5V
◆ 2.5A Continuous Output Current
◆ Adjustable Output Voltage 0.5V to Vin
◆ Up to 95% Efficiency
◆ Synchronizable and Programmable Frequency: 200kHz – 2MHz
◆ Power Good Monitor
◆ <1µA of Shutdown Current
◆ Programmable Soft Start
◆ Programmable Current Limit
◆ Over Temperature protection
◆ -40 to +85 °C Ambient Temperature Range
◆ 4X4mm MLPQ-20 packages- WEEE and RoHS compliant

Applications
◆ Low Voltage Distributed DC-DC Converters
◆ Telecommunication Power Supplies
◆ Portable Equipment
◆ xDSL
