Range,1.23V to 37V (57V for HV Version) ±4% These devices are available in fixed output voltages Max Over Line and Load Conditions of 3.3V, 5V, 12V, 15V, and an adjustable output version. • Specified 3A Output Current • Wide Input Voltage Range, 40V Up to 60V for Requiring a minimum number of external HV Version components, these regulators are simple to use and include internal frequency compensation and a fixed- • Requires Only 4 External Components frequency oscillator. • 52 kHz Fixed Frequency Internal Oscillator The LM2576 series offers a high-efficiency • TTL Shutdown Capability, Low Power Standby replacement for popular three-terminal linear Mode regulators. It substantially reduces the size of the • High Efficiency heat sink, and in some cases no heat sink is required. • Uses Readily Available Standard Inductors • Thermal Shutdown and Current Limit A standard series of inductors optimized for use with Protection the LM2576 are available from several different manufacturers. This feature greatly simplifies the • P+ Product Enhancement Tested design of switch-mode power supplies. APPLICATIONS Other features include a specified ±4% tolerance on output voltage within specified input voltages and • Simple High-Efficiency Step-Down (Buck) output load conditions, and ±10% on the oscillator Regulator frequency. External shutdown is included, featuring • Efficient Pre-Regulator for Linear Regulators 50 μA (typical) standby current. The output switch includes cycle-by-cycle current limiting, as well as • On-Card Switching Regulators thermal shutdown for full protection under fault • Positive to Negative Converter (Buck-Boost) conditions.
