MPQ4487 36V, 6A, Step-Down Converter with Programmable Frequency and Spread Spectrum Option, Dual USB Charging Ports Supporting EN, Fault Indication, and Type-C 5V 3A DFP Mode for Automotive, AEC-Q100 Qualified The Future of Analog IC Technology DESCRIPTION FEATURES Wide 6V to 36V Operating Input Voltage The MPQ4487 integrates a monolithic, step- Range down, switch-mode converter with two USB Selectable Output Voltage current-limit switches and Type-C 5V 3A Line Drop Compensation mode configuration channels for each port. The MPQ4487 achieves 6A of output current with Accurate USB1/USB2 Output Current Limit excellent load and line regulation over a wide 18m/15m Low R Internal Buck DS(ON) input supply range. Power MOSFETs 18m/18m Low R Internal DS(ON) The output of each USB switch is current- USB1/USB2 Power MOSFETs limited. Both USB ports support USB Type-C Frequency Adjustable (250kHz to 2.2MHz) 5V 3A DFP mode, eliminating the need for Frequency Spread Spectrum for outside user interaction. MPQ4487GU-FD-AEC1 Full protection features include hiccup current Forced Continuous Conduction Mode (CCM) limiting, output over-voltage protection (OVP), Operation and thermal shutdown. Load Shedding Versus Temperature Hiccup Current Limit for both Buck and USB The MPQ4487 requires a minimal number of readily available, standard, external EN Control for USB1 and USB2 components and is available in a QFN-26 Fault Indication for USB1 and USB2 (5mmx5mm) package. Supports USB Type-C 5V 3A Mode 8kV HBM ESD Rating for USB1 and USB2 Available in a QFN-26 (5mmx5mm) Package Available in AEC-Q100 Grade 1 Applications USB Hubs USB Type-C Charging Ports All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive.
