NCNR (non cancelable / non returnable)
Step-Up Voltage Regulator, LM2577T-ADJ/NOPB, Texas Instruments
The LM2577T-ADJ/NOPB is a monolithic integrated circuit that provides all of the power and control functions for a step-up (boost), flyback, or forward converter switching regulator. Requiring a minimum number of external components, this regulator is cost-effective and simple to use. Listed in this data sheet is a standard inductor or flyback transformer designed to work with this switching regulator. Included on the chip is a 3.0A NPN switch and its associated protection circuitry, consisting of current and thermal limiting, and undervoltage lockout.
Features
- Requires Few External Components
- 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
Applications
- Simple Boost Regulator
- Flyback and Forward Regulators
- Multiple-output Regulator
