Monolithic Power Systems (MPS) EVQ4321-D-01A Evaluation Board

Monolithic Power Systems (MPS) EVQ4321-D-01A Evaluation Board is designed to demonstrate the capabilities of MPQ4321, a synchronous, step-down switching converter. This board is fully assembled and tested. The MPQ4321 features an open-drain Power Good (PG) signal that indicates whether the output is within 94.5% to 105.5% of nominal voltage. This switching converter is available in a QFN-12 (2mm x 3mm) package with wettable flanks.

Features

  • Operates at 3.3V to 36V input voltage range
  • 2.2MHz switching frequency (fSW)
  • Designed for automotive applications:
    • 42V load dump tolerant
    • Supports 3.1V cold crank
    • 1A of Continuous Output Current (IOUT)
    • -40°C to 150°C operating Junction Temperature (TJ)
    • 150°C absolute maximum TJ
  • Increases battery life:
    • 1µA shutdown current
    • 20µA sleep mode Quiescent Current (IQ)
  • Advanced Asynchronous Modulation (AAM) mode for high efficiency at light loads
  • Power Good (PG) output
  • Over-Current Protection (OCP) with hiccup mode
  • Available in a QFN-12 (2mm x 3mm) package or a QFN-12 (3mm x 4mm) package with wettable flanks
  • Available in AEC-Q100 Grade 1
