The XRP7675 is a 3A capable synchronous current-mode PWM step down (buck) voltage regulator with improved light current load efficiency. A wide 4.5V to 18V input voltage range allows for single supply operations from industry standard 5V and 12V power rails. With a 340kHz constant operating frequency and integrated high and low-side 100mΩ/100mΩ MOSFETs, the XRP7675 reduces the overall component count and solution footprint. Current-mode control provides fast transient response and cycle-by-cycle OCP. An adjustable soft-start prevents inrush current at turn-on, and in shutdown mode the supply current drops to 0.1μA. At light current loads, the XRP7675 operates in Discontinuous Conduction Mode (DCM) and is complemented by a pulse frequency modulation mode (PFM) to provide excellent conversion efficiency. Built-in output over-voltage (open load), over temperature, cycle-by-cycle over-current, under-voltage lockout (UVLO) and  hiccup mode short-circuit protection insures safe operation under abnormal operating conditions. The XRP7675 is offered in a RoHS compliant, “green" / halogen free 8-pin Exposed Pad SOIC package.
