MPS Introduces Industrial Grade,High-Efficiency, Fast-Transient, 3.5A, 36V Synchronous, Step-Down Converter

The MPQ4473 is a fully integrated, high-frequency, synchronous, rectified, step-down, switch-mode converter. It offers a compact solution to achieve a 3.5A, continuous-output current over a wide input-supply range with excellent load and line regulation. It provides fast, transient response and good stability for wide input-supply and load range. The MPQ4473 operates at high efficiency over a wide-output-current load range. 
MPQ4473 has full protection features including, short-circuit protection (SCP), over-current protection (OCP), under-voltage protection (UVP), and thermal shutdown (TSD). 

The MPQ4473 requires minimal, readily available, standard, external components, and is available in a compact 3mmx4mm, 20-pin, QFN package.

FEATURES:

  • Wide 4.5V-to-36V Operating Input Range
  • Guaranteed 3.5A, Continuous Output Current
  • Internal 40mΩ High-Side, 20mΩ Low-Side Power MOSFETs
  • Proprietary Switching-Loss-Reduction Technology
  • 1% Reference Voltage
  • Programmable Soft-Start Time
  • Low Drop-Out Mode
  • 200kHz-to-1MHz Switching Frequency
  • SCP, OCP, UVP, and Thermal Shutdown
  • Output Adjustable from 0.8V to 0.9×VIN
  • Available in a 3mmx4mm, 20-pin, QFN Package
  • Available in AEC-Q100 Grade 1
