SC81531Q

36V/3A, Buck Converter with USB Charging Port Supporting QC3.0 and Type-C 5V@3A DFP Mode, AEC-Q100 Qualified

SC81531Q is a USB Type-C and BC1.2 charging port controller that includes a synchronous step-down converter. It integrates a single USB current-limit switch and achieves 3A of output current across a wide input supply range, with excellent load and line regulation. SC81531Q integrates current-limited USB switch, which supports Quick Charge 3.0 mode, Apple 2.4A Divider mode, DCP schemes for BC1.2, USB Type-C 5V@3A DFP mode and Type-A mode. SC81531Q also integrates negative temperature coefficient (NTC) to monitor the external PCB or other components’ temperatures. Fault condition protections include hiccup current limiting, output over-voltage protection (OVP), DP/DM/CC1/CC2 short-to-battery protection, and thermal shutdown. The SC81531Q is available in 22-pin 4mm X 4mm Wettable Flank Flip-Chip QFN packages.
