TPSM82912 - Low-Noise and Low-Ripple Buck Power Module

General Description

The TPSM8291x devices are a family of highefficiency, low-noise and low-ripple current mode synchronous buck power modules.

Key Features

  • Low output noise < 20 µVRMS (100 Hz to 100 kHz).
  • Low output voltage ripple < 10 µVRMS after ferrite bead.
  • High PSRR of > 65 dB (up to 100 kHz).
  • 2.2-MHz or 1-MHz fixed frequency peak current mode control.
  • Synchronizable with external clock (optional).
  • Integrated loop compensation supports ferrite bead for second stage L-C filter with 30-dB attenuation (optional).
  • Spread spectrum modulation (optional).
  • 3.0-V to 17-V input vol.
