General Description
The MAX1947 is a compact, high-efficiency, step-up DC-DC converter that regulates output voltages from 1.8V to 3.3V to power μP/DSP cores, memory, and I/O rails in 1- and 2-cell alkaline/NiMH/NiCd battery-powered systems. It features an internal 800mA switch and synchronous rectifier to achieve up to 94 efficiency and to eliminate the need for an external Schottky diode.
Features

?? Capability
? Internal Synchronous Rectifier
? High 94 Efficiency
? Fixed Output Voltages: 1.8V, 2.5V, 3V, and 3.3V
? Up to 2MHz Switching Allows Small External
?? Components and Low Output Ripple
? Automatic Pulse Skipping at Light Loads for
?? Extended Battery Life
? Low 70μA (typ) Operating Supply Current
?? (Measured at OUT)
? Low 2μA Logic-Controlled Shutdown
? True Shutdown Fully Discharges Output to Ground
? Uses Only Small Ceramic Capacitors
? 75ms RESET Output Flag
Applications
?? MP3 Players, Pagers, and CD Players
?? PDAs and Organizers
?? Digital Still Cameras
?? Cordless Phones
?? Wireless Mice/Keyboards
?? Portable Medical Equipment
?? Other Battery-Powered Systems
