AT1362A/B
Preliminary Product Information
Synchronous Buck Converter
With Power Good Detector & LDO
General Description
The AT1362A/B provides complete control for
a DC/DC converter optimized for
high-performance microprocessor applications. It
consists of a synchronous step-down DC/DC
converter and a high-speed LDO regulator
connected in series with the DC/DC converter
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 operation frequency is allowing the use of
small surface mount inductor and capacitor. The
internal synchronous switch increases efficiency
and eliminates the need for an external schottky
diode. The AT1362A/B 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.

1. Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the
device. These are stress ratings only, and functional operation of the device at these or any other
conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure
to absolute maximum rating conditions for extended periods may affect device reliability.
2. Device are ESD sensitive. Handling precaution recommended. The Human Body model is a 100pF
capacitor discharged through a 1.5Kresistor into each pin.
