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 overvoltage (open load), over temperature, cycle-by-cycle overcurrent and undervoltage 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.

07/17/2023 | In 2023, MaxLinear will be converting all shipping labels for the parts noted from an EXAR format to MaxLinear’s label. During this transition customers may receive either label. This change affects only shipping and packing labels. This change will not affect the part number, part marking, manufacturing process or manufacturing sites. Only work in progress material will be converted. Existing inventory from MaxLinear’s warehouse, channel sales, distributor, and such, will not be converted. Hence, customers may experience receiving mixed shipments with both Exar and MaxLinear labels for some period until existing inventory of old labels is eventually cleared out. Situation is product to product with no predictable way to determine when all old labels will be exhausted. No change to product form, fit, function and reliability. ADDENDUM A: Fixed MBB label logo for DX204001 to MaxLinear logo. ADDENDUM B: Replaced ‘All other affected products outer box label’ with clearer pictures. Corrected Date Issued (from original PCN) issue date +90 days to August 30, 2023. | PCN & PDN Download |
