ADP2389ACPZ-R7

ADP2389 is a current mode control, synchronous step-down, dc-to-dc regulator. It integrates a 17Mohm high-side power MOSFET and a 4.5Mohm synchronous rectifier MOSFET to provide a high efficiency solution. It operates in pulse frequency modulation (PFM) mode to improve the system efficiency at light load. This device run from an input voltage of 4.5V to 18V and can deliver upto 12A of output current. The output voltage can be adjusted to 0.6V and the switching frequency can be programmed between 200KHz to 2200KHz. This device targets high performance applications that require high efficiency and design flexibility. External compensation and soft start provide design flexibility. It is used in applications such as communication infrastructure, networking and servers, industrial and instrumentation, healthcare and medical, intermediate power rail conversions, DC-to-DC point of load applications.
