Analog Devices Inc. LT7170/LT7170-1 Synchronous Step-Down Regulators
Analog Devices Inc. LT7170/LT7170-1 Synchronous Step-Down Regulators are 16V, single- or dual-phase, silent switcher regulators with digital power system management. These monolithic DC/DC step-down regulators deliver up to 20A of continuous output current. The LT7170/LT7170-1 incorporates the Silent Switcher® architecture, enabling a compact, efficient, and low EMI solution. These regulators are supported by the LTpowerPlay® Graphical User Interface (GUI) tool. Key features include a PMBus/I2C serial interface, differential remote VOUT sense, and fast transient response. These regulators are available in 3.5mm x 4mm 24-lead LQFN package. Typical applications include communications, storage, and industrial systems.
