AM3301

HAXM13030011 Tiny Package, High Efficiency, Step-up DC/DC Converter Features Input Voltage: 1.1V~5.5V Internal MOSFET with high switch current up to 3A 25µA Quiescent (Switch-off) Supply Current Shutdown Mode Supply Current: <5µA 90% Efficiency Up to 450KHz Switching Frequency Using Internal Power Switches SOT-23-6 Package Applications Description The GAM13231001 is a compact, high efficiency, and low voltage step-up DC/DC converter including an error amplifier, ramp generator, comparator, switch pass element and driver in which providing a stable and high efficient operation over a wide range of load currents. It operates in stable waveforms without external compensation. The low start-up input voltage below 1.1V. The high switching rate minimized the size of external components. Besides, the 25µA low quiescent current together with high efficiency maintains long battery lifetime. PDA DSC LCD Panel RF-Tags MP3 Portable Instrument Wireless Equipment The output voltage is set with two external resistors.
