Description
High efficiency monolithic synchronous buck regulator

Features

* High Efficiency: Up to 96% 600mA Output Current 2.5V to 5.5V Input Voltage Range 1.5MHz Constant Frequency Operation No Schottky Diode Required Low Dropout Operation: 100% Duty Cycle Shutdown Mode Draws ≤ 1μA Supply Current Current Mode Operation for Excellent Line and Load Transient Response Over t

Applications

*  100% duty cycle provides low dropout operation, extending battery life in portable systems.   Switching frequency is internally set at 1.5MHz, allowing the use of small surface mount inductors and capacitors.  The internal synchronous switch increases efficiency and eliminates the need for an externa
