3808-2

Product Overview

3808-2 is commonly associated with Analog Devices / Linear Technology LTC3808 series synchronous step-down DC/DC controllers, where 3808-2 may be used as a shortened marking-style or internal reference depending on the exact ordering code. The device is designed to drive external complementary power MOSFETs for high-efficiency buck regulator applications. With No RSENSE™ current sensing, low EMI operation, output tracking support, constant-frequency current-mode architecture and compact DFN / MSOP package options depending on the full part number, it is suitable for distributed power systems, point-of-load regulation, battery-powered equipment, telecom boards, industrial control systems and embedded power supply designs.
