TI Announces TPS65160 Power Management IC

Texas Instruments Inc. (TI, Dallas, TX) announced a new high-performance power management integrated circuit, the TPS65160, which supports all four voltage requirements in a thin-film transistor (TFT) liquid crystal display (LCD) panel. The integrated dc-dc device, which can be powered directly from a 12 V source, is a suitable power manager to safely control the high-current capabilities of large-screen monitor panels and LCD televisions.

The single-chip TPS65160 incorporates two high-efficiency dc-dc converters, two charge pumps, a wide range of safety features, and adjustable power-on sequencing functionality. Supporting input voltages from 8 V to 14 V, the integrated device includes a 2.6 A switch-mode boost converter to provide the source voltage for the system, a 1.8 A non-synchronous step-down converter to provide the logic voltage, and positive and negative charge pump drivers with adjustable regulated output voltages.

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 converter, short-circuit protection of the buck converter, and thermal shutdown to prevent damage caused by excessive heat and power dissipation. Additionally, an under-voltage lockout function shuts down the device at voltages lower than 6 V to provide added protection.

The TPS65160 TFT LCD power converter is available now. The device comes in a 28-pin TSSOP package. Pricing is $2.60 for 1,000-piece quantities.
