Voltage Regulators - DC DC Switching Regulators

48 V regulator100 mAsynchronous buckFly-Buckconstant-on-timeWSON-8

LM25019SD/NOPB is a compact 48 V synchronous buck regulator intended for low-current rails up to 100 mA, with constant-on-time control and an exposed-pad WSON-8 package.

Best for

  • Low-current industrial DC rails
  • Smart meters
  • Telecom bias supplies
  • Fly-Buck isolated bias designs

Avoid if

  • Output current exceeds 100 mA
  • A diode-emulation or pulse-skipping light-load mode is required
  • Feedback ripple cannot be designed or validated

Check before use

  • Validate inductor saturation current against current-limit conditions.
  • Place VIN, VCC, and bootstrap bypass capacitors close to the IC.
  • Connect the exposed pad to RTN and the ground plane for thermal performance.
