Monolithic Power Systems MPQ4559DN | Demoboard EVQ4559DN-00A

Beschreibung

The EVQ4559DN-00A is an evaluation board for the MPQ4559, a high frequency step-down regulator with an integrated power MOSFET. The MPQ4559 integrates a 250mΩ MOSFET that provides 1.5A load current over a wide operating input voltage of 4.5V to 55V. Current mode control provides fast transient response and eases loop stabilization. An internal soft-start prevents inrush current at turn-on. The EVQ4559DN-00A is a fully assembled and tested PCB. It generates a +3.3V output voltage at load current up to 1.5A from an 8V to 55V input range. Switching frequency is set at 500kHz
