Product Details

Demonstration Circuit 725 is a 7A high efficiency, phase-lockable constant frequency buck converter, incorporating the LTC3415 polyphase monolithic synchronous regulator. The DC725 has an input voltage range of 2.375V to 5.5V and an output voltage range from 0.6V to 5V. The output voltage can be set to 1.2V, 1.5V or 1.8V using the appropriate jumper connection, or it can be set to an adjustable value down to 0.6V, the reference voltage of the LTC3415. The DC725 can deliver high power for a monolithic part (up to 7A of output current) due to the high current power switches (28 mΩ of onstate resistance) of the LTC3415.

The LTC3415 can also do polyphase operation, which allows multiple DC725s to be used in parallel for higher current power supplies. Since the parallel LTC3415s can operate out-of-phase, the amount of input and output capacitance required will be minimal.
