Tsum1pfr-lf Datasheet Portable File

  1. Explain how to interpret a datasheet for a hypothetical or niche component using this naming convention.
  2. Provide a template/guide for engineers who encounter an unknown or legacy part number like this in a Bill of Materials (BOM).

Q2: Output voltage is low and buzzing audible (around 1kHz).

A: This indicates the Tsum1pfr-lf is entering burst mode due to light load or feedback loop instability. Increase COMP capacitor from 10nF to 100nF. The -lf version is more sensitive to subharmonic noise.

The datasheet also provides information on the Tsum1pfr-lf's performance characteristics, including: Tsum1pfr-lf Datasheet
