4.5V to 28V Input, 3A Output, Synchronous Buck Converter

SGM61231.pdf

The SGM61231 is a current mode controlled synchronous Buck converter with 4.5V to 28V input range and 3A rated output current. The quiescent current is 190μA (TYP) and the shutdown supply current is 1.2μA (TYP). Two MOSFETs with low R_DSON are integrated to improve the efficiency. Efficiency is maximized through power-save mode (PSM) at light loads. The SGM61231 has adjustable soft-start time for flexible application.

The UVLO level can be adjusted (increased) by an external resistor divider. Secure operation in overload conditions is ensured by cycle-by-cycle current limit, hiccup protection and thermal shutdown protection. The low-side MOSFET has sinking current limit to prevent excessive reverse current.

The SGM61231 is available in a Green SOIC-8 (Exposed Pad) package.
