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

The SGM61233 is a current mode controlled synchronous Buck converter with 4.5V to 28V input range and 3A rated output current. The quiescent current is 320μA (TYP) and the shutdown supply current is 2μA (TYP). Two MOSFETs with low RDSON are integrated to improve the efficiency. Efficiency is maximized through power-save mode (PSM) at light load. The SGM61233A has a wide selectable switching frequency (50kHz to 1500kHz) to allow desired tradeoff between efficiency and component sizes. The SGM61233B has adjustable soft-start time for flexible application. The SGM61233C has a fixed 340kHz switching frequency and a fixed internal 2ms soft-start time.

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 SGM61233 is offered in the Green SOIC-8 (Exposed Pad) and TDFN-3×3-10L packages.
