The LM2576 series are monolithic integrated circuits designed for efficient step-down switching regulator (buck converter) applications. These devices deliver excellent line and load regulation while driving up to 3.0A loads with minimal external components.

• Multiple output voltage options: 3.3V, 5.0V, 12V, 15V, and adjustable (1.23V to 37V)
• ±4% output voltage tolerance across line and load conditions
• Guaranteed 3.0A output current capability
• Wide input voltage range up to 40V
• Requires only 4 external components for operation
• 52kHz fixed frequency internal oscillator
• TTL shutdown capability with low power standby mode
• High efficiency design with thermal shutdown and current limit protection
• Compatible with readily available standard inductors

• High-efficiency step-down (buck) regulators
• Efficient pre-regulators for linear regulators
• On-card switching regulators
• Positive to negative converters (buck-boost)
• Negative boost converters
• Power supply for battery chargers

• High quality products - 100% new and original, ROHS compliant
