1 General Description
This document describes the AS 1340 Evaluation Board.
The AS1340 boost converter contains a 1.4A internal switch in a tiny TDFN-8 3x3mm package. The
device operates from a 2.7V to 5.5V supply, and can boost voltages up to 50V output.

2 Hardware Description
The Evaluation Board has to be supplied via the pins VIN and GND in the range of 2.7V up to 5.5V.
The jumper “EN” section D in the picture below has put to ON (downwards) in order to enable the
chip. On the AS1340 Evaluation Board the output voltage is factory-set to 18V.
