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.
