LM2576HVT-15/NOPB Datasheet PDF - TI

●The LM2576HVT-15/NOPB is a SIMPLE SWITCHER low component count step down (buck) regulator with fixed output in 5 pin TO-220 package. It provides all active functions required for step down (buck) switching regulator. This simple to use regulator includes internal frequency compensation and fixed frequency oscillator. The LM2576HV offers high efficiency replacement for popular three terminal linear regulators. It substantially reduces size of heat sink and in many cases, heat sink is not required. A standard series of inductors optimized for use with LM2574HV are available from several different manufacturers. This feature greatly simplifies the design of switch mode power supplies. This regulator also includes specified ±4% tolerance on output voltage within specified input voltages and output load conditions and ±10% on oscillator frequency. External shutdown function features 50µA (typical) standby current.
