SM5109中文资料Low IQ Single-Inductor and Dual Output for LCD Panel Bias Power Supply数据手册SiliconMitus规格书

描述 Description

The SM5109 is designed to provide power supply with positive and negative output voltage driving TFT-LCD panels up to 10 inches. The device features programmable positive and negative output by an integrated boost converter, LDO and negative charge pump. It also features maximized efficiency by integrating synchronous rectification MOSFETs for the boost converter, LDO and negative charge pump. The device operates in single-cell Li-Ion, Ni-Li and Li-Polymer batteries with the input range of 2.7 V to 5.0 V. The SM5109 is available in a 15-bump, 1.23 mm x 2.03 mm(0.4 mm pitch) WLCSP package.
