1FEATURES DESCRIPTIONThe LM2575 series of regulators are monolithic
23• 3.3V, 5V, 12V, 15V, and Adjustable Output integrated circuits that provideall the active functions
Versions fora step-down (buck) switching regulator, capableof
• Adjustable Version Output Voltage Range, drivinga 1A load with excellent line and load
1.23Vto 37V (57V for HV Version) ±4% regulation. These devices are availablein fixed output
voltagesof 3.3V, 5V, 12V, 15V, and an adjustable
Max Overoutput version.
– Line and Load ConditionsRequiring a minimum number of external
• Specified 1A Output Current components, these regulators are simpleto use and
• Wide Input Voltage Range, 40V upto 60V for include internal frequency compensation anda fixed-
HV Version frequency oscillator.
Requires Only4 External Components The LM2575 series offers a high-efficiency
• 52 kHz Fixed Frequency Internal Oscillator replacement for popular three-terminal linear
TTL Shutdown Capability, Low Power Standby regulators.It substantially reduces the sizeof the
Mode heat sink, and in many cases no heat sinkis
required.
• High Efficiency standard seriesof inductors optimized for use with
• Uses Readily Available Standard Inductorsthe LM2575 are available from several different
• Thermal Shutdown and Current Limit manufacturers. This feature greatly simplifies the
Protection designof switch-mode power supplies.
• P+ Product Enhancement Tested Other features includea specified ±4% tolerance on
output voltage within specified input voltages and
APPLICATIONS output load conditions, and ±10% on the oscillator
Simple High-Efficiency Step-Down (Buck) frequency. External shutdownis included, featuring
Regulator 50 μA (typical) standby current. The output switch
includes cycle-by-cycle current limiting, as well as
• Efficient Pre-Regulator for Linear Regulators thermal shutdown for full protection under fault
• On-Card Switching Regulators conditions.
