Part Number : LM2575
Function : 52kHz Simple 1A Buck Regulator
Package : TO-220, DIP 16 Pin Type
Maker : Micrel
Pinouts : 
Description :
The LM2575 series of monolithic integrated circuits provide all the active fuctions for a step-down(buck) switching regulator. Fixed versions are available with a 3.3V, 5V, 12V, fixed output. Adjustable versions have an output voltage range from 1.23V to 37V. Both versions are capable of driving a 1A load with excellent line and load regulation.
These regulators are simple to use because they require a minimum number of external components and include internal frequency compensation and a fixed-frequency oscillator.
Features
