AS1345
18V, High Efficiency, DC-DC Step-Up
Converter
General Description
The AS1345 high efficiency DC-DC step-up converter contains
an internal N-channel and an internal P-channel output
isolation switch.
The device operates from a 2.9V to 5.0V supply and can boost
voltages up to 18V.
A hysteretic control scheme is used to provide the highest
operating efficiency over a wide range of input and output load
conditions. The internal MOSFET switches reduce the external
component count and a high switching frequency allows the
use of tiny surface mount components.
The AS1345 employ a factory set current limit to reduce ripple
and external component size in low output current applications.
With a 500mA current limit the AS1345 is capable of providing
20mA @ 18V output.

Built-in safety features protect the internal switches and output
components from fault conditions. Additional power-saving
attributes include a very low quiescent current and a true
shutdown mode.
