Texas Instruments’ tiny, high-performance power conversion IC works in tandem with processing platforms that use TI’s Smart-Reflex power and performance management technologies. Designed to extend battery life in 3G phones and other portable electronics, the flexible converter features a 3.4Mbps I2C communications interface and ultra-fast transient response from a tiny chip scale package.
The TPS62350 synchronous, step-down dc/dc converter supports up to 800mA over the input voltage range of a single-cell Li-Ion battery. The device’s integrated communications interface allows it to adjust output voltage between 0.75 and 1.53V, efficiently supporting TI’s advanced DSPs, Smart-Reflex technologies enabled OMAP processors, and other processor core power supplies in cellphones, PDAs and digital still cameras. It also supports handheld computers that use Intel’s XScale processors.
The TPS62350 can operate in a power-save mode at lightload currents, and can be placed in a shutdown mode where power consumption is reduced to less than 1μA.
