LM1577/LM2577 Series SIMPLE SWITCHER Step-Up Voltage Regulator June 1999 LM1577/LM2577 Series SIMPLE SWITCHER ® Step-Up Voltage Regulator General Description The LM1577/LM2577 are monolithic integrated circuits that provide all of the power and control functions for step-up (boost), flyback, and forward converter switching regulators. The device is available in three different output voltage versions: 12V, 15V, and adjustable. Requiring a minimum number of external ponents, these regulators are cost effective, and simple to use. Listed in this data sheet are a family of standard inductors and flyback transformers designed to work with these switching regulators. Included on the chip...
