The FAN5037 is a high power, switch-mode DC-DC controller that provides efficient power for all low-voltage applications. This controller has a built-in Soft Start feature which offers system protection during power-up by reducing both inrush current and output overshoot. When combined with the appropriate external circuitry, the FAN5037 can deliver load currents as high as 13A at efficiencies as high as 88%. The FAN5037 can generate output voltages from 1.2V up to 3.6V using external resistors.
