The SGM61451 is a frequency programmable, internally compensated, Buck regulator with an integrated high-side MOSFET. It provides up to 5A output current capability over a wide input range from 4V to 40V, which accommodates a variety of Buck applications in an industrial input environment. Only 49μA (TYP) sleep-mode quiescent current makes the SGM61451 suitable for battery powered systems. An ultra-low 2.3μA (TYP) shutdown current can further prolong battery life.
The SGM61451 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.
The SGM61451 employs adjustable soft-start time to prevent high start-up 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 SGM61451 is available in Green SOIC-8 (Exposed Pad) and TDFN-4×4-10L packages.
