Programmable DC power supply

Block diagram

Overview

Whether you are designing a 50-W or 1-kW DC lab supply, our integrated circuits and reference designs help you create programmable DC power supply systems.

Design requirements

Modern programmable DC power supply designs often require:

  • Power levels ranging from 50 W to over 1 kW at various voltage and current levels.
  • Support for variable rise/fall times, nano-level resolution and mixed signal I/Os.
  • Precise DC and AC operation with low drift over time.
  • Support for existing and upcoming programmable wired interfaces.
