MPQ4488 36V, 6A, Step-Down Converter with Programmable Frequency and Spread Spectrum Option, Dual USB Charging Ports Supporting DCP 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 MPQ4488 integrates a monolithic, step- Range down, switch-mode converter with two USB Selectable Output Voltage: 5.1V, 5.17V, and current-limit switches and charging port 5.3V identification circuitry for each port. The MPQ4488 achieves 6A of output current with 90mV Line Drop Compensation excellent load and line regulation over a wide Accurate USB1/USB2 Output-Current Limit input supply range. 18m/15m Low R Internal Buck DS(ON) Power MOSFETs The output of each USB switch is current- 18m/18m Low R Internal DS(ON) limited. Both USB ports support DCP schemes USB1/USB2 Power MOSFETs for battery charging specification (BC1.2), Frequency Adjustable (250kHz to 2.2MHz) divider mode, 1.2V/1.2V mode, and USB Type- Frequency Spread Spectrum for C 5V 3A DFP mode, eliminating the need for MPQ4488GU-FD-AEC1 outside user interaction. Forced CCM Operation Full protection features include hiccup current Load Shedding versus Temperature limiting, output over-voltage protection (OVP), Hiccup Current Limit for both Buck and USB and thermal shutdown. Supports DCP Schemes for BC1.2, Divider The MPQ4488 requires a minimal number of Mode, and 1.2V/1.2V Mode readily available, standard, external Supports USB Type-C 5V 3A DFP Mode components and is available in a QFN-26 8kV HBM ESD Rating for USB, DP, and (5mmx5mm) package. DM Available in a QFN-26 (5mmx5mm) Package Available in AEC-Q100 Grade 1 APPLICATIONS USB Dedicated Charging Ports (DCP) USB Type-C Charging Port All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive.
