LT8698SJV#WPBF

LT®8698S is a compact high efficiency synchronous monolithic step-down switching regulator. Programmable cable drop compensation maintains accurate 5V VBUS regulation even for USB sockets separated from the LT8698S by a long cable such as an automobile wiring harness. Silent Switcher Technology and selectable spread-spectrum modulation provide ultralow EMI/EMC. The LT8698S supports a wide variety of portable device charger profiles including USB BC 1.2 CDP, DCP, and SDP as well as common proprietary profiles. Integrated VBUS reset and VBUS regulator disable functions support USB OTG functionality. It includes two parallel 10nF capacitors from VIN to PGND for improved EMI/EMC performance. Applications are automotive USB, Industrial USB.
