Product Description

The EVQ4456-QT-00A is an evaluation board for the MPQ4456, a high frequency step-down regulator with an integrated power MOSFET.

The MPQ4456 integrates a 300mΩ MOSFET that provides 1A load current over a wide operating input voltage of 3.8V to 36V.

Current mode control provides fast transient response and eases loop stabilization. An internal soft-start prevents inrush current at turn-on.

The EVQ4456-QT-00A is a fully assembled and tested PCB. It generates a +3.3V output voltage at load current up to 1A from an 8V to 36V input range. Switching frequency is set at 500kHz.

Product Features

  • 1A Output Current
  • Programmable Switching Frequency up to 4MHz
  • Wide 8V to 36V Operating InputRange
  • Adjustable Output from 0.8V
  • Fully Assembled and Tested

Parametrics


1A, 4MHz, 36V Step-Down Converter

The MPQ4456 is a high frequency step-down switching regulator with an integrated internal high-side high voltage power MOSFET. It provides 1 A output with current mode control for fast loop response and easy compensation. The wide 3.8V to 36V input range accommodates a variety of step-down applications, including those in automotive systems. A 120µA operational quiescent current is suitable for use in battery-powered applications. Special controlled circuitry allows the MPQ4456 to maintain PWM operation at low output currents. This lowers noise by reducing the pulse skipping. By switching at 4MHz, the MPQ4456 prevents EMI (Electromagnetic Interference) noise problems, such as those found in AM radio and ADSL applications. The MPQ4456 is available in thin 10-pin 3mm x 3mm TQFN package.
