Designed to extend battery life in portable electronics products, the flexible converter features a 3.4 Mb/s, I2C communications interface, exhibiting ultrafast transient response in a tiny chip-scale package. The device's integrated I2C communications interface enables it to adjust its output voltage between 0.75 V and 1.53 V, efficiently supporting TI's advanced digital signal processors (DSPs), SmartReflex technologies-enabled OMAP processors like TI's OMAP3430 processor, and other processor core power supplies.

The TPS62350 can operate in a power-save mode at light load currents, and can be placed in a shutdown mode where the power consumption is reduced to less than 1 microampere. The device's serial interface is compatible with fast/standard and high-speed mode I2C specification, which allows data transfer at up to 3.4 Mb/s. The dynamic voltage-scaling feature allows the TPS62350 to adjust voltage levels in 12.5 mV steps and seamlessly switch to an efficiency-optimized light power factor mode, a transient-optimized fast PFM mode or a forced PFM mode. Key features of the TPS62350 include 88% efficiency at 3 MHz operation, 800 mA output current at a 2.7-input voltage, excellent load and line transient response, 2% PWM dc voltage accuracy and 35 ns minimum on-time.

The converter can be supplied in a 12-pin, 2.2 mm x 1.4 mm, chip-scale package or in a 10-pin, 3 mm x 3 mm QFN package. Samples are available; volume production is scheduled for June. The TPS62350 is priced at $2.05 in 1000-piece quantities.
