SGM6232_buck 5v step-down module

SGM6232 is a current mode buck converter with internal power MOSFET switch. The switching frequency of the device is fixed at 1.4MHz, and the output voltage range is adjustable from 0.8V to 28V. It can efficiently deliver up to 2A of output load current over a wide input supply range of 4.5V to 38V with excellent load and line regulation response. The SGM6232 has a peak efficiency of 91% when operating efficiently. The regulator consumes less than 18μA of shutdown supply current. Protection features include circulating current limiting and thermal shutdown. The device also includes internal soft-start and externally adjustable soft-start features to limit inrush current and prevent overshoot of the output voltage. The SGM6232 comes in a green SOIC-8 (Exposed Pad) package, which also reduces the external components of the device to complete a 2A step-down DC/DC converter solution.
