Evaluation KitGET THIS KIT
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 300m? 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.
