Introduction

AI Translation

The LM2577S/T is a monolithic integrated circuit that provides all power and control functions for boost, flyback, and forward converter switching regulators. The device is available in three output voltage versions: 12V, 15V, and adjustable. These regulators require a minimum number of external components, making them cost-effective and easy to use. Integrated on-chip is a 3.0A NPN switch with associated protection circuitry, including current and thermal limiting and undervoltage lockout. Additional features include a 52 kHz fixed-frequency oscillator requiring no external components, a soft-start mode to reduce surge current during startup, and current-mode control for improved input voltage and output load transient rejection. The LM2577S is available in a TO-263-5L package. The LM2577T is available in a TO-220-5L package.
