Description
The EVQ4559DN-00A is an evaluation boardfor the MPQ4559, a high frequency step-downregulator with an integrated power MOSFET.The MPQ4559 integrates a 250mΩ MOSFETthat provides 1.5A load current over a wideoperating input voltage of 4.5V to 55V.Current mode control provides fast transientresponse and eases loop stabilization. Aninternal soft-start prevents inrush current atturn-on.The EVQ4559DN-00A is a fully assembled andtested PCB. It generates a +3.3V output voltageat load current up to 1.5A from an 8V to 55Vinput range. Switching frequency is set at500kHz.ELECTRICAL
