Power chip does the lot for TFT LCDs
A new high-performance power management integrated circuit efficiently supports all four voltage requirements in a thin film transistor liquid crystal display panel
Texas Instruments has developed a high-performance power management integrated circuit (IC) that efficiently supports all four voltage requirements in a thin film transistor (TFT) liquid crystal display (LCD) panel. The highly integrated DC/DC device, which can be powered directly from a 12V source, is the ideal power manager to safely control high current capabilities of today's large screen monitor panels and LCD TVs.

TI's single-chip TPS65160 incorporates two high-efficiency DC/DC convertors, two charge pumps, a wide range of safety features and adjustable power-on sequencing functionality.
Supporting input voltages from 8 to 14V, the integrated device includes a 2.6A switch-mode boost convertor to provide the source voltage for the system, a 1.8A nonsynchronous step-down convertor to provide the logic voltage, and positive and negative charge pump drivers with adjustable regulated output voltages to ensure optimal picture quality.
The TPS65160 provides fast transient response and maintains up to 95% power conversion efficiency to help save energy usage.
The TPS65160 also includes safety features such as over-voltage protection of the boost convertor; short-circuit protection of the buck convertor; and thermal shutdown to prevent damage caused by excessive heat and power dissipation.
Additionally, an undervoltage lockout function shuts down the device at voltages lower than 6V to provide added protection.
The TPS65160 TFT LCD power convertor is available today in volume from TI and its authorised distributors.
The device comes in a 28-pin TSSOP package.
Suggested resale pricing in quantities of 1000 is $2.60.
