XRP7665 3A 18V Synchronous Step-Down Converter March 2013 GENERAL DESCRIPTION The XRP7665 is a synchronous current-mode PWM step down (buck) regulator capable of a constant output current up to 3 Amps. A wide 4.50V 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/90mΩ MOSFETs, the XRP7665 reduces the overall component count and solution footprint. Current-mode control provides fast transient response and cycle-by-cycle current limit. An adjustable soft-start prevents inrush current at turn-on, and in shutdown mode the supply current drops to 0.1µA.
