TI Intros TPS65130 OLED Power Management ICs

Texas Instruments Inc. (TI, Dallas, TX) announced its first organic light-emitting diode (OLED) display power conversion integrated circuit (IC), the TPS65130, which is a dual-output, dc-dc converter optimized to generate a positive output voltage up to 15 V, and a negative output voltage down to -12 V with programmable sequencing.

With a power conversion efficiency up to 89 percent, the new driver supports advanced OLED and charge-coupled device sensor bias supply applications in battery-powered equipment such as cellular phones, PDAs, digital cameras and camcorders. The TPS65130 supports an input-voltage range of 2.7 V to 5.5 V, which allows it to be powered directly from a single-cell, lithium-ion battery or multi-cell, nickel-metal hydride, nickel-cadmium and alkaline batteries.

The TPS65130 features a small 4 mm x 4 mm QFN package, and a minimum number of external components. The TPS65130 operates at a low quiescent current and with a fixed-frequency, pulse-width modulation of minimum 1.25 MHz, which allows the use of tiny 4.7 µH inductors. Independent enable pins allow power-up and power-down sequencing for both outputs.

The TPS65130 OLED power converter is available now and comes in a 24-pin, 4 mm x 4 mm, QFN package. Suggested resale pricing in quantities of 1,000 is $2.95.
