SGM6230
SGM6230 is 385kHz Buck Converter manufactured by SG Micro.
DESCRIPTION
FEATURES
The SGM6230 is a current-mode buck converter with an internal power MOSFET switch. This device has a fixed switching frequency of 385k Hz. It can efficiently provide up to 2A output load current over a wide input supply range from 4.5V to 38V with good load and line regulation responses.
In addition, the SGM6230 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 SGM6230 is available in Green SOIC-8 (Exposed Pad) package and also minimizes the external ponents of the device to plete a 2A buck DC/DC converter solution.
