Analog Devices LTC4090EDJC Demonstration Board

The Analog Devices LTC4090EDJC Demonstration Board (DC1210A) is a compact evaluation kit built around the LTC4090EDJC USB power manager with Li‑Ion charger, designed to demonstrate the LTC4090’s dual-input power management and Bat‑Track high‑voltage buck regulator on a single board. The board supports two input sources and is specified for 6 V to 36 VIN with protection for up to 60 V transients, enabling testing of USB-powered devices that must also charge a lithium‑ion battery. The LTC4090EDJC is a 22‑lead DFN package (6 mm × 3 mm) with a lead-free finish, and the device on the board can deliver up to 1.5 A IOUT for battery charging or system load under LTC4090 control. Documentation for the DC1210A, including a Quick Start Guide, confirms its role as an evaluation circuit for LTC4090 features and performance, making setup straightforward for developers evaluating USB power management in portable electronics.
