LT3840 Demo Board DC1909A

Analog Devices LT3840 Demo Board DC1909A is an evaluation board featuring a 150kHz, 60V current mode DC-DC step-down converter example circuit based on the LT3840 wide input range synchronous regulator controller with an accurate current limit. The LT3840 Demo Board DC1909A operates from a V_IN range of 4.5V to 60V, survives an 80V transient, and outputs 3.3V at 20A (66W). An integrated buck-boost switching regulator generates a 7.5V bias supply voltage for the MOSFET gate drive and IC power to increase the overall efficiency by reducing the power loss.
