FATUM mini DC-DC converter is an easy-to use 32 V, 2 A synchronous step-down regulator. With a wide input ranges from 4 V to 32 V, it is suitable for various industrial applications for power conditioning from unregulated sources. Peak-current-mode control is employed to achieve simple control-loop compensation and cycle-by-cycle current limiting. A quiescent current of 75 µA makes the device suitable for battery-powered systems. The device has an option for constant frequency FPWM mode to achieve small output-voltage ripple at light load. Protection features include cycle by- cycle current limit, hiccup-mode short-circuit protection, and thermal shutdown due to excessive power dissipation.
