TCS3511

Programmable Dual Output LCD Bias for Smartphone and Tablets

产品描述

The TCS3511 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.

It features 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 120mA. An LDO and charge pump generate dual outputs at +5V(default) and -5V(default), whose voltages can be programmed via an I2Ccompatible interface. Optimized step-up, LDO and charge pump converters maximize conversion efficiency, exceeding 85%.

TCS3511 integrates all compensation and soft-start circuitry, which results in a simpler and smaller solution with much fewer external components. High switching frequency (1.2MHz) allows the use of a smaller inductor and capacitor to further reduce the solution size.

The I2C compatible interface allows to control the positive and negative outputs from+4V to +6V and -4V to -6V, respectively, as well as programming additional registers on the device.

The device is a RoHS compliant 15-Ball 2.07mm X 1.24mm X 0.64mm WLCSP package.
