MagnaChip Semiconductor
General Description
The MAP7102 is designed to support positive / negative driven TFT-LCD panels. The two output rails are usually connected to the Source Driver IC. The device uses a single inductor scheme in order to provide the user the smallest solution size possible as well as high efficiency. With its input voltage range of 2.8V to 5.5V, it is optimized for products powered by single-cell batteries and output currents up to 50mA. The device is delivered in a WLCSP package of 15 balls
