Description

The MPQ1530 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 MPQ1530 is available in a tiny 3x3mm, 16-pin QFN package.
