DESCRIPTION
The SGM61060Q is an efficient, 6A, synchronous Buck converter with integrated power MOSFETs and wide 2.9V to 6V input range. This current mode control device is optimized for high density applications with minimal number of external components. High switching frequency, up to 2MHz, can be chosen to reduce 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 (HS) MOSFET current is cycle-by-cycle limited for overload protection. The low-side (LS) MOSFET sourcing current is also limited to prevent current runaway. The low-side switch also has a sinking current limit which will turn the switch 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 SGM61060Q is AEC-Q100 qualified (Automotive Electronics Council Standard Q100 Grade 1) and the use of this device is suitable for automotive applications.
The SGM61060Q is available in a Green TQFN-3×3-16EL package.
