The LM2576 series of monolithic integrated circuits provide all the Active functions for a step-down (buck) switching regulator. Fixed versions are available with a 3.3V, 5V, or 12V fixed output. Adjustable versions have an output voltage range from 1.23V to 37V. Both versions are capable of driving a 3A load with excellent line and load regulation.
Additional Features:
3.3V, 5V, 12V, and adjustable output versions
Voltage over specified line and load conditions:
Fixed version: ±3% max. output voltage
Adjustable version: ±2% max. feedback voltage
Guaranteed 3A output current
Wide input voltage range: 4V to 40V
Wide output voltage range: 1.23V to 37V
Requires only 4 external components
52kHz fixed frequency internal oscillator
Low power standby mode IQ typically < 200μA
80% efficiency (adjustable version typically > 80%)
Uses readily available standard inductors
Thermal shutdown and current limit protection
100% electrical thermal limit burn-in
