GENERAL DEscriptION
The SGM6130 is a current-mode step-down regulator with an internal power MOSFET. This device has a fixed switching frequency of 385kHz. It can efficiently provide up to 3A output load current over a wide input supply range from 4.5V to 28.5V with good load and line regulations responses.
In addition, the SGM6130 is highly efficient with peak efficiency at 94% when in operation. The shutdown supply current consumed by the regulator is less than 18μA. Protection features include cycle-by-cycle current limit and thermal shutdown. The device also includes an internal soft-start and an external adjustable soft-start function to limit the inrush current and prevent the overshoot of output voltage.
The SGM6130 is available in a Green SOIC-8 (Exposed Pad) package and also minimizes the external components of the device to complete a 3A buck DC/DC converter solution.
