Low Noise and Small Form Factor Power Management Reference Design for CC256X Bluetooth Controller


Design files


The TIDA-00598 features a low noise and size optimized power management solution which regulates 5V to 3.3V and 1.8V required to operate the CC256X Bluetooth controller.  These regulated voltage rails can also be used to power other components in the system as microcontroller, level shifters and sensors.

  • Quiet power supply
    • Low Noise: >10 µVRMS@ BW = 10 Hz to 100 kHz
    • High PSRR: >75dB @ f = 1 kHz
  • Small footprint ICs with few decoupling capacitors
  • Low noise output voltage supply: 3.3V and 1.8V
  • Operating temperature range: -40°C to 85°C
  • Input voltae supply range: 3.7 V to 5.5 V
  • Cost optimized linear regulators

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
