EVQ4487-U-00A Smart, Dual USB Charging Port Power Converter with Programmable Frequency for Automotive, AEC-Q100 Qualified The Future of Analog IC Technology DESCRIPTION FEATURES The EVQ4487-U-00A is an evaluation board for Wide 6V to 36V Operating Input-Voltage MPQ4487, which integrates a monolithic step- Range down switch-mode converter with two USB Selectable Output Voltage: 5.1V, 5.17V and current-limit switches and Type-C 5V 3A 5.3V mode configure channel for each port. It 90mV Line Drop Compensation achieves 6A max output current over a wide Accurate USB1/USB2 Output-Current Limit input-supply range with excellent load and line 18m/15m Low R Internal Buck DS(ON) regulation. Power MOSFETs 18m/18m Low R Internal The output of the USB switch is current limited. DS(ON) USB1/USB2 Power MOSFETs Both USB ports support TYPE-C 5V 3A DFP Load Shedding versus Temperature Mode eliminating outside user interaction. Hiccup Current Limit for both Buck and USB Fault condition protection includes hiccup Supports USB TYPE-C 5V 3A Mode current limiting, output OVP, and thermal shutdown (TSD).
