The XRP6668 is a dual channel synchronous current mode PWM step-down (buck) converter capable of delivering up to 1Amp of current per channel and optimized for portable battery-operated operations.

Based on a current mode 1.5MHz constant frequency PWM control scheme, the devices reduce the overall component count and solution footprint as well as provide a low output voltage ripple and excellent line and load regulation. Both devices also implement a PFM mode to improve light load efficiency as well as a 100% duty cycle LDO mode. Output voltage is adjustable to as low as 0.6V with better than 3% accuracy while a low quiescent current supports the most stringent battery operation conditions. Built-in over temperature and under voltage lock-out protections insure safe operations under abnormal operating conditions.

XRP6668 is available in a RoHS compliant, “green” halogen free 8-pin SOIC package.

Distribution Date Description File
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.
