TI Presents TPS6106x Family of Boost DC Converters
Texas Instruments Inc. (TI, Dallas, TX) announced a family of synchronous boost converters that can power up to five series white light-emitting diodes (LEDs) in small battery-powered, hand-held devices. The ultra-small, 1.5 mm x 1.5 mm integrated circuits allow portable designers to implement the smallest possible inductor-based solution to power and control white LED backlights in smart phones, PDAs, digital still cameras and other hand-held electronics.
The new TPS6106x family of specialized dc-dc converters support input voltages from 2.7 V to 6 V, and can power up to three-series, four-series and five-series LEDs. The TPS61060, TPS61061 and TPS61062 devices integrate a 400 mA power MOSFET and synchronous rectifier, eliminating the need for an external series Schottky diode. Additionally, the 1 MHz fixed switching frequency allows the converters to work with smaller, low-value external components, such as a 10 µH inductor and a 220 nF output capacitor.
The TPS61060, TPS61061 and TPS61062 are available today in volume from TI and its authorized distributors. Each device is available in an 8-pin, QFN or 8-pin, chip scale package. Suggested resale pricing in quantities of 1,000 is $1.35 for the TPS61060, $1.40 for the TPS61061 and $1.45 for the TPS61062.
