The XRP7659 is a current-mode PWM step-down (buck) voltage regulator capable of delivering an output current up to 1.5Amps. A wide 4.5V to 18V input voltage range allows for single supply operation from industry standard 5V, 9.6V and 12V power rails.
With a 1.4MHz constant operating frequency, integrated high-side MOSFET and loop compensation, the XRP7659 reduces the overall component count and solution footprint. Current-mode control provides fast transient response and cycle-by-cycle current limit. An integrated soft-start prevents inrush current at turn-on, and in shutdown mode the supply current drops to 0.1µA.
Built-in output over voltage (open load), over temperature, cycle-by-cycle over-current and under voltage lockout (UVLO) protection insure safe operation under abnormal operating conditions.
The XRP7659 is a pin and function compatible device to Monolithic Power Systems MP2359 for input voltages below 18V.
The XRP7659 is offered in a RoHS compliant, "green"/halogen free 6-pin SOT-23 package.
