Product Information
Product Overview
The LM2577T-ADJ/NOPB is a SIMPLE SWITCHER® low component count Step-up Voltage Regulator provides all of the power and control functions for step-up (boost), flyback and forward converter switching regulators. This regulator is available in adjustable voltage version and requiring a minimum number of external components. This monolithic integrated circuit voltage regulator associated protection circuitry, consisting of current and thermal limiting and under-voltage lockout. Other features includes a 52kHz 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.
- Requires few external components
- NPN output switches 3A can stand-off 65V
- Current-mode operation for improved transient response, line regulation and current limit
- Soft-start function reduces in-rush current during start-up
- Output switch protected by current limit, under-voltage lockout and thermal shutdown
