BANGALORE, INDIA: Texas Instruments Inc. (TI) has introduced the TPS65070 and TPS65073 family of single-chip power management integrated circuits for portable electronics.
The new power management unit (PMU) implements all sequencing and default options to power today’s leading processors, including TI’s OMAP and digital signal processors.
The TPS65070 and TPS65073 devices result in a 50-percent 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, 200-mA LDOs; white LED backlighting to support up to 5-inch LED displays; I2C communications interface; 10-bit A/D converter; touch-screen interface and an integrated 1.5-A linear battery charger.
TI’s new PMUs support the following processors with easy-to-design reference designs:
* TPS65070: OMAP-L1x, TMS320C6742, TMS320C6746 and TMS320C6748 devices.
* TPS65073 and TPS650731: OMAP35x processors.
