The LM2576 series of regulators are monolithic integrated
        circuits that provide all the active functions for a step-down
        (buck) switching regulator, capable of driving 3A load with
        excellent line and load regulation.
  
          Storage Temperature Range ?65°C to +150°C
          Maximum Junction Temperature 150°C
Efficiency: VIN = 12V, ILOAD = 3A 77%
