LM2577, LM2 Datasheet - National Semiconductor

LM2577 SIMPLE SWITCHER Step-Up Voltage Regulator

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 .

LM2577 Features

* include a 52 kHz fixed-frequency oscillator that requires no external components, a soft start mode to reduce in-rush current during start-up, and current mode control for improved rejection of input voltage and output load transients. Features Requires few external components NPN output switches 3
