DESCRIPTION
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.
