Product Description

The EVQ4487-U-00A is an evaluation board for MPQ4487, which integrates a monolithic step-down switch-mode converter with two USB current-limit switches and Type-C 5V@3A mode configure channel for each port. It achieves 6A max output current over a wide input-supply range with excellent load and line regulation.

The output of the USB switch is current limited. Both USB ports support TYPE-C 5V@3A DFP Mode eliminating outside user interaction.

Fault condition protection includes hiccup current limiting, output OVP, and thermal shutdown (TSD).

Product Features

  • Wide 6V to 36V Operating Input-Voltage Range
  • Selectable Output Voltage: 5.1V, 5.17V and 5.3V
  • 90mV Line Drop Compensation
  • Accurate USB1/USB2 Output-Current Limit
  • 18mΩ/15mΩ Low RDS(ON) Internal Buck Power MOSFETs
  • 18mΩ/18mΩ Low RDS(ON) Internal USB1/USB2 Power MOSFETs
  • Load Shedding versus Temperature
  • Hiccup Current Limit for both Buck and USB
  • Supports USB TYPE-C 5V@3A Mode


36V, 6A, Step-Down Converter with Programmable Frequency and Spread Spectrum Option, Dual USB Charging Ports Supporting EN, Fault Indication, and Type-C 5V@ 3A DFP Mode for Automotive, AEC-Q100 Qualified

The MPQ4487 integrates a monolithic, step-down, switch-mode converter with two USB current-limit switches and Type-C 5V @ 3A mode configuration channels for each port. The MPQ4487 achieves 6A of output current with excellent load and line regulation over a wide input supply range.
The output of each USB switch is current-limited. Both USB ports support USB Type-C 5V @ 3A DFP mode, eliminating the need for outside user interaction.
Full protection features include hiccup current limiting, output over-voltage protection (OVP), and thermal shutdown.
The MPQ4487 requires a minimal number of readily available, standard, external components and is available in a QFN-26 (5mmx5mm) package.
