Compact, efficient, 24-V input auxiliary power supply reference design for servo drives

Overview

TopologyBuck Converter
Input voltage3.8-36 V
Output 15 V / 3 A
IC revisionE2

Description

This reference design showcases a method to generate power supplies required in a servo or AC drive including the analog and digtal I/O interfaces, encoder supply, isolated transceivers and digital processing block. This design also implements protection against input reverse polarity, output overload and short circuit conditions.

Features

  • Powered from an external protective extra-low voltage (PELV) power supply of 24 V ±20%
  • Industrial eFuse at supply input providing programmable UV/OV, reverse polarity protection, output overload and SC protection
  • Synchronous buck DC/DC converter with integrated switch optimized for >90% efficiency and compact size
  • PSR flyback with integarted switch to generate isolated voltage rails for communication and digital I/Os
  • Programmable voltage output to support multiple encoder types
  • Output voltage rails: 24 VISO, 5 VISO, ±12 V, 5 V, 3.3 V, 2.5 V, 1.2 V with load and line regulation of <±1%

Typical applications

  • Servo drive control module
