Description/Ordering Information

The LM2575 greatly simplifies the convenience of switching power supplies and provides all the buck (buck) switching regulators required for an IC design. Accepting a wide input voltage range and available in adjustable output versions, the LM2575 integrates a switch that provides 1 line with excellent line and load regulation load current. The device also offers internal frequency compensation, a fixed frequency oscillator, cycle-by-cycle current limiting, and thermal shutdown. In addition, manual shutdown can also be done via an external ON/OFF terminal.

The LM2575 is a popular three-terminal linear regulator better choice. Due to its high efficiency, the size of the fins is greatly reduced, and in many cases the absence of them is necessary. Optimized for use with a standard series from several different inductor manufacturers, the LM2575 is greatly simplified, requiring minimal external components that operate only 4 to 6 In addition, the design of the switch-mode power supply is required.

The LM2575 features a temperature range of -40°C with a virtual junction of -125°C
