MPS MP1530DQ-LF-Z

转换器，TFT LCD2.7V ~ 5.5V多重

Overview

The MP1530DQ/DM-LF-Z combines a triple output step-up converter with linear regulators to provide a complete DC/DC solution. It is designed to power TFT LCD panels from a regulated 3.3V or 5V supply. This device integrates a 1.4MHz fixed frequency step-up converter with positive and negative linear regulators. The step-up converter switch node drives two charge pumps, which supply powers to their respective linear regulators. The positive and negative linear regulator inputs can withstand up to 38V and down to -20V, respectively. A single on/off control enables all 3 outputs. The outputs are internally sequenced at startup for ease of use. An internal soft-start prevents input overload at startup. Cycle-by-cycle current limiting reduces component stress. The MP1530DQ/DM-LF-Z is available in a tiny 3mm x 3mm, 16-pin QFN package or a 16-pin TSSOP package.
