TPS65186RGZT TI PMIC | 48-VQFN(7x7) | 4-Ch DC-DC, 2 LDOs, VCOM Buffer

Product Overview

The TPS65186RGZT is a highly integrated power management IC (PMIC) from Texas Instruments, designed specifically for thin-film transistor (TFT) LCD displays. It provides all necessary supply voltages and a VCOM buffer in a single 48-pin VQFN package (7x7 mm). The device includes four DC-DC converters (boost, buck, and two charge pumps), two low-dropout regulators (LDOs), and a programmable VCOM buffer with gamma correction. This solution simplifies power supply design for medium-to-large TFT LCD panels used in industrial, automotive, and medical applications.

Detailed Technical Specifications

Key Features

• Integrated 4-channel DC-DC converter: boost (up to 15 V), buck (adjustable), positive charge pump (up to 30 V), negative charge pump (down to -15 V)
• Two LDOs: one for analog supply (3.3 V), one for logic supply (1.8 V)
• Programmable VCOM buffer with 10-bit resolution and gamma correction
• I2C interface for dynamic voltage scaling and sequencing
