Introduction

AI Translation

The LM2577S-ADJ is a monolithic integrated circuit that provide all of the power and control functions for step-up (boost), flyback, and forward converter switching regulators. Requiring a minimum number of external components, these regulators are cost effective, and simple to use. Included on the chip is a 3.0A NPN switch and its associated protection circuitry, consisting of current and thermal limiting, and undervoltage lockout. Other 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. The LM2577S-ADJ is available in TO263-5L package.
