The LTC3406AES5#TRMPBF is a 65V, low-noise, high-efficiency, dual-channel synchronous buck regulator designed by Analog Devices. It is housed in a 5mm x 6mm 16-lead eTSSOP package and can deliver up to 2A of output current. The regulator features a wide input voltage range of 2.25V to 65V, a high efficiency of up to 90%, and a low shutdown quiescent current of only 1µA. It also has a dual-phase operation which provides an output current of 4A with two phases driven in parallel. Other features of the regulator include adjustable current limit, frequency synchronization, soft-start, and cycle-by-cycle current limit. This makes it ideal for powering high current systems from a single voltage source.
