The XRP7725 is a quad channel Digital Pulse Width Modulated (DPWM) step-down (buck) controller. A wide 4.75V to 5.5V and 5.5V to 25V input voltage dual range allows for single supply operation from standard power rails.

With integrated FET gate drivers, two LDOs for standby power and a 105kHz to 1.23MHz independent channel to channel programmable constant operating frequency, the XRP7725 reduces overall component count and solution footprint and optimizes conversion efficiencies. A selectable Digital Pulse Frequency Mode (DPFM) and low operating current result in better than 80% efficiency down to 10mA load provides support for portable and Energy Star compliant applications. Each XRP7725 output channel is individually programmable down to a minimum 0.6V with a resolution of 2.5mV, and configurable for precise soft-start and soft-stop sequencing, including delay and ramp control.

The XRP7725 operation is fully controlled via an SMBus-compliant I2C interface allowing for advanced local and/or remote reconfiguration, full performance monitoring and reporting as well as fault handling.

Built-in independent output overvoltage, over temperature, overcurrent and undervoltage lockout protections insure safe operation under abnormal operating conditions.

The XRP7725 is offered in a RoHS compliant, “green”/halogen free 44-pin TQFN 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.

For best gate drive performance, it is recommended to route GL_RTN (PGND) together with its GL pin like a differential pair instead of just connecting GL_RTN to GND at the IC and subjecting it to ground noise. Routing them together cancels out any noise, inductive and electromagnetic field effects between these two traces. See ANP-32 Practical Layout Guidelines for PowerXR Designs http://www.exar.com/appnote/anp32 page 8 for more information.
