LM2575HVT-15 P+

3.3V, 5V, 12V, 15V, and Adjustable Output
integrated circuits that provide all the active functions Versions for a step-down (buck) switching regulator, capable of
? Adjustable Version Output Voltage Range, driving a 1A load with excellent line and load
? 1.23V to 37V (57V for HV Version) ?4% regulation. These devices are available in fixed output
Max Over voltages of 3.3V, 5V, 12V, 15V, and an adjustable
output version. ? Line and Load Conditions
? Specified 1A Output Current Requiring a minimum number of external
components, these regulators are simple to use and ? Wide Input Voltage Range, 40V up to 60V for include internal frequency compensation and a fixed- HV Version frequency oscillator.
? Requires Only 4 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 size of the
Mode heat sink, and in many cases no heat sink is
required. ? High Efficiency
? Uses Readily Available Standard Inductors A standard series of inductors optimized for use with
the LM2575 are available from several different ? Thermal Shutdown and Current Limit manufacturers. This feature greatly simplifies the Protection design of switch-mode power supplies.
