The EV1542DK-TFT-00A is the evaluation board for TFT applications using the MP1542. The MP1542 can be operated at 700KHz or 1.3MHz allowing for easy filtering and low noise. An external compensation pin gives the user flexibility in setting loop dynamics, which allows the use of small, low-ESR ceramic output capacitors. Soft-start results in small inrush current and can be programmed with an external capacitor. The MP1542 operates from an input voltage as low as 2.5V and can generate 12V at up to 500mA from a 5V supply.

The EV1542DK-TFT-00A provides VOUT1 from the boost output and also derives VOUT3 (positive) and VOUT2 (negative) from the charge pumps off of the boost switching node.
