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 VOUT from the boost output and also derives VP (positive) and VN (negative) from the charge pumps off of the boost switching node.
