MaxLinear XRP7665

Description

The XRP7665 is a synchronous current mode PWM step down (buck) regulator capable of a constant output current up to 3Amps. 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 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.

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

The XRP7665 is a pin and function compatible device to MP1484 and a 3A pin to pin upgrade to XRP7664.
