The XRP7662 is a synchronous voltage mode PWM step-down (buck) regulator capable of a constant output current up to 12Amps. A wide 5V to 22V single input voltage range allows for single supply operations from industry standard 5V, 12V and 18V power rails. Operations down to 3V are supported with an additional biasing voltage.

With a 300kHz constant operating frequency and integrated high and low side switch, the XRP7662 reduces the overall component count and solution footprint. In addition to a 1% output set-point accuracy, this device provides high efficiency, low ripple and excellent line and load regulation. An enable function and soft-start feature allow for controlled power up sequencing implementation.

Built-in current limiting, UVLO, output short-circuit and over temperature protection insure safe operation under abnormal operating conditions.

The XRP7662 is offered in a RoHS compliant, lead free 26-pin 7mm x 4mm DFN 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.
