EVQ4560-Q-00A 2A, 55V, 2MHz Step-Down Converter Evaluation Board The Future of Analog IC Technology DESCRIPTION FEATURES The EVQ4560-Q-00A is an evaluation board for 2A Output Current the MPQ4560, a high frequency step-down Programmable Switching Frequency up to regulator with an integrated power MOSFET. 2MHz Wide 8V to 55V Operating Input Range The MPQ4560 integrates a 250m MOSFET Adjustable Output from 0.8V that provides 2A load current over a wide Fully Assembled and Tested operating input voltage of 4.5V to 55V. Current mode control provides fast transient APPLICATIONS response and eases loop stabilization. An High Voltage Power Conversion internal soft-start prevents inrush current at Game Machines turn-on. Automotive Systems The EVQ4560-Q-00A is a fully assembled and Industrial Power Systems tested PCB. It generates a +5V output voltage Distributed Power Systems at load current up to 2A from an 8V to 55V input Printer Systems range. Switching frequency is set at 700kHz.
