SGM61180 4.5V to 18V Input, 8A, Synchronous Buck Converter GENERAL DESCRIPTION The SGM61180 is an efficient, 8A, synchronous Buck converter with integrated power MOSFETs and a wide 4.5V to 18V input range. This current mode control device is optimized for high density applications with minimal number of external components. High switching frequency, up to 2000kHz, can be chosen to lessen the solution size by smaller inductor and capacitors. This device can be used as a standalone or tracking power supply. The SS/TR pin can be used to control the output voltage startup ramp or as an input for tracking. Power supply sequencing for two or more power supplies is possible by using the enable input (EN) and the open-drain power good output (PG) signals.
