TI Single-chip Power Management Units For Portable Electronics Cut Board Space In Half

September 20, 2009 by Jeff Shepard

Texas Instruments Inc. (TI) introduced the TPS6507x family of single-chip, power management integrated circuits for portable electronics. The new power management units (PMUs) implement all sequencing and default options to power today’s leading processors, including TI’s OMAP™ and digital signal processors.

The TPS65070 and TPS65073 devices are said to result in a 50% smaller dc-dc implementation versus a discrete design by integrating three highly efficient, 2.25-MHz, 1.5-A dc-dc step-down converters that support core processor, memory and I/O voltages; two general purpose, 200mA LDOs; white LED backlighting to support up to 5-inch LCD displays; I²C communications interface; 10-bit analog-to-digital converter; touch-screen interface and an integrated 1.5A linear battery charger.

TI’s new PMUs support the following processors with easy-to-use reference designs: TPS65070: OMAP-L1x, TMS320C6742, TMS320C6746 and TMS320C6748 devices; as well as TPS65073 and TPS650731: OMAP35x processors.

The TPS65070 and TPS65073 devices are available in volume production from TI and its authorized distributors. The devices come in a 6 x 6 x 0.4mm, 48-pin, leadless, thermally enhanced QFN package with a suggested resale price of $3.95 in 1,000-unit quantities. Samples, evaluation modules and application notes are available.
