Vishay SiC46X Synchronous microBUCK® new devices in VSH

SiC46X devices contain all the silicon needed to design a high performance buck regulator in a 5mm by 5mm package

Vishay SiC46X SIC461 Product Picture

Ideal for applications needing high voltage inputs or required to work with various battery voltage stacks, SiC46X devices contain all the silicon needed to design a high performance buck regulator in a 5mm by 5mm package.

The devices can also replace non-synchronous buck regulators, which provide lower efficiency in larger footprints. The buck regulators allow one part to be used for a variety of input voltages, reducing the need to qualify multiple devices and improving safety margins for rugged and reliable operation.


Key features

  • Single supply operation from 4.5 V to 60 V input voltage
  • Adjustable output voltage down to 0.8 V
  • Scalable 2A (SiC464), 4A (SiC463), 6A (SiC462), 10A (SiC461)
  • ± 1 % output voltage accuracy at -40 °C to +125 °C


Additional features

  • Feature high and low side MOSFETs with five times lower on-resistance than competing devices o Combined with their ultra low quiescent current, this results in high efficiencies over the full load range
    • Synchronous buck topology reduces component count and weight
  • High efficiency reduces power losses, enabling system designers to increase power density
  • Combined with the superior thermal design of the MLP55-27L package, the devices’ high efficiency enables cooler operation for improved long term reliability, while eliminating the need for a heatsink o Allows designers to shrink the PCB size, simplify thermal management, and reduce system costs
  • Wide input voltage range is ideal for several applications: o Loosely regulated nominal 24 V, 36 V, and 48 V inputs in noisy industrial environments
    • Voltages up to 60 V cover the kick-back transients caused by motors in power tools, battery operated vehicles, robotic vacuum/garden equipment
    • Wide range of battery packs up to 14S and fuel cells
    • Battery management systems
    • High voltage battery chargers
    • After market automotive applications
  • All devices are footprint-compatible to provide designers with a scalable solution
  • Voltage mode COT architecture delivers ultra fast transient response with minimum output capacitance and tight ripple regulation at light loads
  • Compatible with any output capacitor type
  • Low jitter reduces EMC and EMI in noise sensitive applications



  • Industrial and Automation
  • Home Automation
  • Industrial compting
  • Robots
  • Base station power supplies
  • Wall transformer regulation
