MaxLinear Introduces Smart Power Stage with Current and Temperature Monitoring

  • 20A integrated power stage extends telemetry to lower power rails
  • Small 4mm x 5mm QFN package integrates the driver, high-side (HS) and low-side (LS) MOSFET’s

CARLSBAD, Calif.--(BUSINESS WIRE)-- MaxLinear, Inc. (NYSE: MXL), a leading provider of radio frequency (RF), analog and mixed-signal integrated circuits for the connected home, wired and wireless infrastructure, and industrial and multimarket applications, today introduced its first Smart Power Stage (SPS). The fully optimized XR78021 integrates a synchronous buck gate driver and HS/LS MOSFETs that support up to 20A output current in a compact 4mm x 5mm QFN package. The package design is optimized to provide very low thermal impedance and excellent EMI performance by minimizing parasitic inductances. The XR78021 is targeting conversions from 12V down to as low as 0.6V to meet the requirements of processors and chipsets used in servers, networking and telecommunications equipment.

The XR78021 integrates temperature monitoring and a current sense amplifier with temperature compensation supporting DCR current sensing. The temperature and current telemetry features allow system implementers to design reliable and robust solutions for mission critical end equipment.

"The XR78021 expands our ability to meet the needs of server and enterprise markets,” said Joseph Tseng, MaxLinear Director of Marketing, Power Management. "The XR78021 can be used on the +1 phase in multiphase controllers to power 12A to 20A rails and provides real-time temperature monitoring and reporting on critical CPU, memory and system power rails. In addition to MaxLinear’s success of 15A and 20A constant on-time regulators in the server market, the XR78021 gives customers the option to have telemetry of current and temperature. When using the XR78021’s smaller form factor 4mm x 5mm package instead of the standard 5mm x 6mm footprint in systems, customers can realize much needed space savings.”


The XR78021 is available now in a RoHS compliant, 4mm x 5mm QFN package. Samples and evaluation boards are available. For more information, visit
