The SP7652 is a synchronous step-down switching regulator optimized for high efficiency. The part is designed to be especially attractive for dual supply, 12V step-down with 5V used to power the controller. This lower Vcc voltage minimizes power dissipation in the part. The SP7652 is designed to provide a fully integrated buck regulator solution using a fixed 600kHz frequency, PWM voltage mode architecture. Protection features include UVLO, thermal shutdown and output short-circuit protection. The SP7652 is available in the space saving DFN package.

  • 2.5V to 28V step-down achieved using dual input
  • Output boltage down to 0.8V
  • 6A output capability
  • Built in low RDSON power FETs (15 mΩ typ)
  • Highly integrated design, minimal components
  • 600 kHz fixed frequency operation
  • UVLO detects both VCC and VIN
  • Over temperature protection
  • Short-circuit protection with auto restart
  • Wide BW Amp allows type II or III compensation
  • Programmable soft-start
  • Fast transient response
  • High efficiency: greater than 92% possible
  • Nonsynchronous start up into a pre-charged output
  • Small 7mm x 4mm DFN package

06/25/2024 Product Discontinuation Notice
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.

Vin and LX nodes are directly connected to internal MOSFETs. Monitor the LX node. If there is excessive ringing then try an RC snubber across the bottom FET, say 2.2nF in series with 2- to 3 Ohms.
