TPS65070RSLR

Product Summary

The TPS65070RSLR is a single chip Power Managemen IC for portable applications consisting of a batter charger with power path management for a single Li-Ion or Li-Polymer cell. The charger can either be supplied by a USB port on pin USB or by a dc voltage from a wall adapter connected to pin AC . Three highly efficient 2.25MHz step-down converters are targeted at providing the core voltage, memory and I/O voltage in a processor based system. The TPS65070RSLR enters a low power mode at ligh load for maximum efficiency across the wides possible range of load currents. For low noise applications the TPS65070RSLR can be forced into fixed frequency PWM using the I2C interface. The applications of the TPS65070RSLR include Portable Navigation Systems, PDAs, Pocket PCs, OMAP and Low Power DSP Supply.
