LM2575HVT-5.0 P+

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.

Other features include a 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 shutdown is included, featuring
Regulator 50 ?A (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
