The EV1530-Q-00A evaluation board is designed to demonstrate the capabilities of MPS’ MP1530 triple output step-up converter which is capable of powering a TFT panel from a regulated 3.3V or 5V.

The MP1530 includes a 1.4MHz fixed-frequency step-up converter and a positive and negative linear regulator. The linear regulators are powered from a charge-pump driven by the step-up converter switch node (SW).

A single on/off control enables all 3 outputs. The outputs are internally sequenced at power on and power off for ease of use. An internal soft-start prevents overloading the input source at startup. Cycle-by-cycle over current protection limits component overstress.
