AS1383
200mA, 3.5MHz DC-DC Step-Up
Converter
General Description
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.
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 VOUT is pre-programmed in 100mV steps,
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.
