MAXREFDES1174: -24V/150mA, Negative Output Power Supply Using the MAX17501

MAXREFDES1174

参考设计免责声明 参照  重要声明和免责声明  涵盖参考设计和其他Maxim资源

描述

The MAXREFDES1174 is centered around the MAX17501 ultra small, high-efficiency, high-voltage, synchronous stepdown DC-DC converter with integrated MOSFETs. This design provides a -24V output and up to 150mA of load current with an input voltage range of 22V to 30V. Unlike a traditional design, this reference design is configured to work in a buck-boost topology to produce negative output voltage from positive input voltage.

Industrial control equipment such as programmable logic controllers, I/O modules, mass flow controllers, and various other sensors and supporting systems use analog components like amplifiers and multiplexers that operate on negative supply voltage. The MAXREFDES1174 is designed to demonstrate the operation and principles on how to use the MAX17501 can be used to provide a negative supply voltage.

Key Features

  • No Schottky-synchronous operation for high efficiency and reduced cost
  • Ultra-compact layout
  • All-ceramic capacitors
  • Reduces power dissipation
