The SP6120 is a fixed frequency, voltage mode, synchronous PWM controller designed to work from a single 5V or 3.3V input supply. Sipex's unique "AnyFET™" Technology allows the SP6120 to be used for resolving a multitude of price/performance trade-offs. It is separated from the PWM controller market by being the first controller to offer precision, speed, flexibility, protection and efficiency over a wide range of operating conditions.

  • Optimized for single supply, 3V - 5.5V applications
  • High efficiency: greater than 95% possible
  • "AnyFET TM" technology: capable of switching either PFET or NFET high side switch
  • Selectable Discontinuous Conduction Mode (DCM) or Continuous Conduction Mode (CCM) for use in battery or bus applications
  • Fast transient response
  • 16-pin TSSOP, small size
  • Accurate 1% reference over line, load and temperature
  • Accurate 10% frequency
  • Accurate, rail to rail, 43mV, overcurrent sensing
  • Resistor programmable frequency
  • Resistor programmable output voltage
  • Capacitor programmable soft-start
  • Low quiescent current: 950μA, 10μA in shutdown
  • Hiccup overcurrent protection

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.
