ADP2386ACPZN-R7

ADP2386 is a synchronous step-down, DC-to-DC regulator with an integrated 44mohm, high-side power MOSFET and an 11mohm, synchronous rectifier MOSFET to provide a high-efficiency solution in a compact package. This device uses a peak current mode and constant frequency pulse-width modulation (PWM) control scheme for excellent stability and transient response. The switching frequency can be programmed from 200KHz to 1.4MHz. To minimize system noise, the synchronization function allows the switching frequency to be synchronized to an external clock. This regulator targets high-performance applications that require high efficiency and design flexibility. External compensation and an adjustable soft start function provide design flexibility. Application includes communications infrastructure, networking and servers, industrial and instrumentation, healthcare, and medical, intermediate power rail conversion, and DC-to-DC point-of-load applications.
