TPS60120EVM-174, Battery-Powered, Dual-Output Power Supply EVM for DSP's

TPS60120EVM-174, Battery-Powered, Dual-Output Power Supply EVM for DSP's. Power supply solution is comprised of a TPS60120 low-power dc/dc converter and a TPS70751 dual LDO regulator with integrated supervisory and power-up sequencing circuitry. The converter generates a 3.3V output voltage and can provide up to 200 mA of output current. The 3.3V converter output voltage is the input for both of the regulators on the TPS70751. Using its power-up sequencing circuitry, the TPS70751 powers up the 1.8V output before the 3.3V output. The supervisory circuitry reset signal is low until both voltages are within a certain threshold of regulation. This configuration is designed to provide a complete power management solution for battery powered DSP, ASIC and other digital applications where two independent supply voltages are required
