The OCP2131 is designed to support positive / negative driven TFT-LCD panels up to10” at least (from SFF to MFF like tablets).

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.

a highly integrated step-up DC-DC converter with wide input voltage range from 2.7V to 5.5V. It is optimized for products powered by single-cell batteries (Li-Ion, Ni-Li, and Li-Polymer) and symmetrical output currents up to 80mA. An LDO and charge pump generate dual outputs at +5V (default) and -5V (default), whose voltages can be programmed via an I2C compatible interface. Optimized step-up, LDO and charge pump converters maximize conversion efficiency, exceeding 85%. OCP2131 integrates all co.
