Single-chip power management ICs for portable electronics from TI

TI has introduced the TPS6507x family, a new single-chip power management integrated circuits for portable electronics. The power management units (PMUs) implement sequencing and default options to power processors, including TI's OMAP and digital signal processors.

The TPS65070 and TPS65073 devices result in a 50-percent small DC/DC implementation versus a discrete design by integrating three 2.25-MHz, 1.5-A DC/DC step-down converters that support core processor, memory and I/O voltages, and two 200-mA 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 1.5-A 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
TPS65073 and TPS650731: OMAP35x processors

Package: 6 mm x 6 mm x 0.4 mm, 48-pin, leadless, thermally enhanced QFN package
Price: with a suggested resale price of $3.95 for 1k pieces
Availability: Now
