LM2577T-15/NOPB 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 

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.



LM2577T-15/NOPB Features


Requires Few External Components

NPN Output Switches 3.0A, can Stand off 65V

Wide Input Voltage Range: 3.5V to 40V

Current-mode Operation for improved Transient Response, Line Regulation, and Current Limit

52 kHz Internal Oscillator

Soft-start Function Reduces In-rush Current During Start-up

Output Switch Protected by Current Limit, Under-voltage Lockout, and Thermal Shutdown



LM2577T-15/NOPB Applications


Simple Boost Regulator

Flyback and Forward Regulators

Multiple-output Regulator
