The SGM61130 is an efficient, 4A, 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.
The high-side MOSFET current is cycle-by-cycle limited for overload protection. The low-side MOSFET sourcing current is also limited to prevent current runaway. The low-side switch also has a sinking current limit that turns it off if an excessive reverse current flows through it.
Thermal shutdown protection is activated to prevent damage to the device when the junction temperature is above the shutdown threshold.
The SGM61130 is available in a Green TQFN-3.5×3.5-14L package.
