Description

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.
