GENERAL DESCRIPTION
Internal synchronous rectifier with low RDS(ON) dramatically reduces conduction loss at PWM mode. The internal synchronous switch increases efficiency while eliminate the need for an external Schottky diode.The switching ripple is easily smoothed-out by small package filtering elements due to a fixed operation frequency of 1.5MHz. This along with small SOT-23-5 package provide small PCB area application. Other features include soft start, lower internal reference voltage with 2% accuracy, over temperature protection, and over current protection. FEATURES
High Efficiency: 96% 1.5MHz Fixed-Frequency PWM Operation Adjustable Output From 0.6V to VIN 800mA Output Current, 1.1A Peak Current No Schottky Diode Required 100% Duty Cycle Low Dropout Operation Available in SOT23-5 Package Short Circuit and Thermal Protection Over Voltage Protection Low than 1µA Shutdown Current APPLICATIONS
