The TPS75005 is a complete power management solution for Texas Instruments’ C2000 real-time microcontrollers and other DSP, FPGA, and ASIC MCUs. The device has been tested with and meets TI’s F2833x (DELFINO), F2823x, F281x, and F280x/F2801x power requirements.

All of these C2000 controllers require ±5% power-rail accuracy. With the combination of high-accuracy, low-dropout regulators (LDOs) and dedicated SVSs, the device allows for a ±5% power supply to the C2000 with a power-good (PG) signal. (For more details, see Application Report SBVA032, LDO+SVS Combined Accuracy.)

Two power outputs are controlled by an integrated sequencer circuit. A single EN logic input signal makes sure that the power-up and power-down requirements of the C2000 controllers are met. The sequencer includes a soft-start for both LDOs to avoid inrush current. A third rail monitor is provided for general-purpose monitoring (for example, to monitor input voltage).

A quick-start guide (SBVA030) is available with step-by-step instructions for connection to a C2000 controller.

The TPS75005 is available in a 5-mm × 5-mm QFN package, yielding a compact total solution size with high power dissipation capability.
