1.0 A, Adjustable Output Voltage, Step?Down Switching Regulator
The LM2575 series of regulators are monolithic integrated circuits ideally suited for easy and convenient design of a step?down switching regulator (buck converter). All circuits of this series are capable of driving a 1.0 A load with excellent line and load regulation. These devices are available in fixed output voltages of 3.3 V, 5.0 V, 12 V, 15 V, and an adjustable output version.
Features
? 3.3 V, 5.0 V, 12 V, 15 V, and Adjustable Output Versions
? Adjustable Version Output Voltage Range of 1.23 V to 37 V ±4 Maximum Over Line and Load Conditions
? Guaranteed 1.0 A Output Current
? Wide Input Voltage Range: 4.75 V to 40 V
? Requires Only 4 External Components
? 52 kHz Fixed Frequency Internal Oscillator
? TTL Shutdown Capability, Low Power Standby Mode
? High Efficiency
? Uses Readily Available Standard Inductors
? Thermal Shutdown and Current Limit Protection
? Moisture Sensitivity Level (MSL) Equals 1
? Pb?Free Packages are Available*
Applications
? Simple and High?Efficiency Step?Down (Buck) Regulators
? Efficient Pre?Regulator for Linear Regulators
? On?Card Switching Regulators
? Positive to Negative Converters (Buck?Boost)
? Negative Step?Up Converters
? Power Supply for Battery Chargers
