AS1382

1A, High Efficiency, DC-DC Step Down

Converter

The AS1382 is a high-efficiency, constant-frequency

synchronous buck converter available in adjustabe- and

fixed-voltage versions. The wide input voltage range (2.7V to

5.5V), automatic powersave mode and minimal external

component requirements make the AS1382 perfect for any

single Li-Ion battery-powered application.

General Description

Typical supply current with no load is 95μA and decreases to

0.04μA in shutdown mode.

An internal synchronous switch increases efficiency and

eliminates the need for an external Schottky diode. The

internally fixed switching frequency (2MHz, 3MHz or 4MHz)

allows the usage of small surface mount external components.

Very low output voltages can be delivered with the internal

0.58V feedback reference voltage.

The AS1382 is available in a 6-pin WL-CSP package.

Ordering Information and Content Guide appear at end of

datasheet.
