Features & Applications
The XRP7664 is asynchronous current mode PWM step down (buck) regulator capable of a constantoutput current up to 2 Amps. A wide 4.75 to 18 V input voltage range allows forsingle supply operations from industry standard 5 and 12 V power rails.



With a 340 kHz constant operating frequency and integrated high and low side120 / 110 mΩ MOSFETs, the XRP7664 reduces the overall component count andsolution footprint. Current-mode control provides fast transient response andcycle-by-cycle current limit. An adjustable soft-start prevents inrush currentat turn-on, and in shutdown mode the supply current drops to 0.1 uA.

Built-in output over voltage (open load), over temperature, cycle-by-cycleover current and under voltage lockout (UVLO) protections insure safe operationsunder abnormal operating conditions.
