Monolithic Power Systems (MPS) EVBL2171-J-00A Evaluation Board

Monolithic Power Systems (MPS) EVBL2171-J-00A Evaluation Board demonstrates the MP2171 and the MPQ2171. The board features an integrated MPS power inductor. The MP2171 is a low-voltage, high-frequency, step-down switch-mode converter with integrated, internal power MOSFETs. It can achieve up to 1A of highly efficient output current (IOUT) across a wide 2.5V to 5.5V input voltage (VIN) range, with constant-on-time (COT) control for fast loop response.

Features

  • Wide 2.5V to 5.5V operating input voltage (VIN) range
  • Up to 1A output current (IOUT)
  • 40μA quiescent current (IQ)
  • 90mΩ and 50mΩ internal power MOSFETs
  • 2.6MHz default switching frequency (fSW) with 3.3V input and 1.8V output
  • Enable (EN) and power good (PG) for power sequencing
  • Stable with low ESR ceramic output capacitors
  • Internal soft-start (SS)
  • Cycle by Cycle over-current protection (OCP)
  • Shutdown auto-discharge
  • Short-circuit protection (SCP) with hiccup mode
  • Thermal shutdown
  • Available in a TSOT23-8 package

Applications

  • Automotive infotainment systems
  • Automotive clusters
  • Automotive telematics
  • Low-voltage I/O power systems
  • Handheld and battery-powered systems
