AS1343
42V, 1-2 Cells, Micropower, DC-DC Boost Converter

Revision 1.04

Datasheet
1 General Description
The AS1343 boost converter contains a 1.4A internal
switch in a tiny TDFN-10 3x3mm package. The device
operates from a 0.9V to 3.6V supply, and can boost volt-
ages up to 42V output.
The output voltage can easily be adjusted by an external
resistor divider.
The AS1343 uses a unique control scheme providing
the highest efficiency over a wide range of load condi-
tions. An internal 1.4A MOSFET reduces external com-
ponent count, and a fixed high switching frequency
(1MHz) allows for tiny surface-mount components.
The AS1343 also features power-OK circuitry which
monitors the output voltage.
Additionally the AS1343 features a low quiescent supply
current and a shutdown mode to save power. During
shutdown an output disconnect switch separates the
input from the output.
The AS1343 is ideal for LCD or OLED panels with low
current requirements and can also be used in a wide
range of other applications.
The device is available in a low-profile TDFN-10 3x3mm
package.
