Applications
Power Supply for Slim Type devices General Description The AT1362A/B/C provides complete control for a DC/DC converter optimized for hight-performance mi- croprocessor applications. It consists of a synchronous step-down DC/DC converter and a high-speed LDO regulator connected in series with the DC/DC con- verter output. A power good detector and LDO ON/OFF control is also built-in(metal option). DC/DC converter is operated on current mode architecture for excellent line and load transient response. 1MHz op- eration frequency is allowing the use of small surface mount inductor and capacitor. The internal synchro- nous switch increases efficiency and eliminates the need for an external schottky diode. The AT1362A/B/C is a family of low-noise synchronous step-down DC/DC converters that is ideally suited for systems powered form a 1-cell Li-ion battery or from a 3-cell to 4-cell NiCd, NiMH, or alkaline battery. It can also be used to USB-based power system.
