The TPS65910A1RSL is an integrated Power Management IC dedicated to applications powered by one Li-Ion or Li-Ion polymer battery cell or 3-series Ni-MH cells or by a 5V input, it requires multiple power rails. The device provides three step-down converters, one step-up converter and eight LDOs and is designed to support the specific power requirements of OMAP-based applications. Two of the step-down converters provide power for dual processor cores and are controllable by a dedicated class-3 SmartReflex interface for optimum power savings. The third converter provides power for the I/Os and memory in the system. The device includes eight general-purpose LDOs providing a wide range of voltage and current capabilities. The LDOs are fully controllable by the I2C interface. In addition to the power resources, the device contains an embedded power controller (EPC) to manage the power sequencing requirements of the OMAP systems and an RTC.
