説明
The MAXREFDES1180 is centered around the MAX17501 ultra small, high-efficiency, high-voltage, synchronous stepdown DC-DC converter with integrated MOSFETs. This design provides a -12V output and up to 150mA of load current with an input voltage range of 4.5V to 5.5V. Unlike a traditional design, this reference design is configured to work in an inverting 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 MAXREFDES1180 is designed to demonstrate the operation and principles on how to use the MAX17501 to provide a negative supply voltage.
機能と利点
