GENERAL DESCRIPTION
The EV1541DJ-TFT-00A is the evaluation
board for TFT applications using the MP1541.
The MP1541 is a 5-pin thin SOT23 current
mode step up converter intended for small, low
power applications. The MP1541 switches at
1.3MHz and allows the use of tiny, low cost
capacitors and inductors 2mm or less in height.
Internal soft start results in small inrush current
and extends battery life. The MP1541 operates
from an input voltage as low as 2.5V and can
generate 12V at up to 200mA from a 5V supply.
The EV1541DJ-TFT-00A provides V
OUT
from
the boost output and also derives V
P
(positive)
and V
N
(negative) from the charge pumps off of
the boost switching node.
