EV0055中文资料美国芯源数据手册PDF规格书

DESCRIPTION

The EV0055 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).
