AS1382
1A, High Efficiency, DC-DC Step Down
Converter
General Description
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.
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.
