Analog Devices LT7170

The LT7170/LT7170-1 are monolithic DC/DC synchronous stepdown regulators that deliver up to 20 A of continuous output current. The LT7170-1 option has two switching phases that are connected to two inductors to drive a single-regulated output supply. The quick, clean, low-overshoot switching edges deliver high efficiency while minimizing electromagnetic interference (EMI) emissions.
