AS1383

200mA, 3.5MHz DC-DC Step-Up

Converter

The AS1383 is a synchronous, high efficiency DC-DC boost

converter running at a constant frequency of 3.5MHz. This very

high oscillator frequency allows the usage of a low profile

inductor with only 1μH. This results in a very small board space

requirement for the complete solutions including all external

components.

General Description

AS1383 generates an output voltage range from 2.7V to 5.0V.

In adjustable output voltage variant, the output voltage is

selected with an external resistor divider. In fixed output

voltage variant the V

is pre-programmed in 100mV steps,

OUT

and the external resistor divider is not needed.

AS1383 supports input voltages down to 2.7V. The device

provides an output current of 200mA. To support high

efficiency across the entire load range the AS1383 is equipped

with a synchronous rectifier and features a power save mode

for light loads.

To avoid harmful deep discharge of the battery during

shutdown the AS1383 is equipped with an output disconnect

function.

The AS1383 is available in a 6-pin WL-CSP package with 0.4mm

pitch.

Ordering Information and Content Guide appear at end of

datasheet.
