The SGM61434xQ is a frequency programmable, internally compensated Buck converter with an integrated high-side MOSFET. It provides up to 3.5A output current capability over a wide input range from 4V to 40V, which accommodates a variety of Buck applications in an automotive input environment. Only 47μA (TYP) sleep-mode quiescent current makes the SGM61434xQ suitable for battery powered systems. An ultra-low 2.1μA (TYP) shutdown current can further prolong battery life.
The SGM61434xQ uses peak-current mode control with constant switching frequency to provide optimal output voltage accuracy and fast loop response. Switching frequency is widely adjustable, which enables optimization of either efficiency or solution size. Internal loop compensation makes it easy to use and eliminates many external components. Frequency spread spectrum version (SGM61434BQ) is also available for reducing EMI.
The SGM61434xQ employs adjustable soft-start time to prevent high startup inrush current. An enable pin is provided for simplification of on/off control and system power sequencing. Protection features include thermal shutdown, input under-voltage lockout, cycle-by-cycle current limit, output over-voltage protection.
The device is AEC-Q100 qualified (Automotive Electronics Council (AEC) standard Q100 Grade 1) and it is suitable for automotive applications.
The SGM61434xQ is available in Green SOIC-8 (Exposed Pad) and TDFN-4×4-10AL packages.
