FEATURES • Internal Power Switch • Output Voltage up to 20V • Up to 89% Efficiency • Low 0.08μA Shutdown Supply Current • Internal Current Limit • Thermal Shutdown • Available in 5-Pin SOT-23 Package APPLICATIONS • Handheld Computers, PDA’s • Cell Phones • Digital Still and Video Games • Small LCD Displays GENERAL DESCRIPTION The AMS6104 is an adjustable step-up DC/DC converter with a 1Amp internal switch. The low quiescent current of typical 300μA, makes AMS6104 attractive for battery operated applications. AMS6104 operates at switching frequencies of 500 kHz allowing for easy filtering and low noise. The reference voltage is set at 1.23V. Internally compensated and internal soft-start minimizes the number of external components necessary. It operates from 1.3V to 15V supply and it is thermally and over current protected. The AMS6104 is available in SOT23-5 leads package.
