Микросхемы и комплектующие ADP1850ACPZ-R7

DC/DC контроллер , 2.75В до 20В, 2 выхода, синхронный понижающий, 1.5МГц, LFCSP-32

The ADP1850ACPZ-R7 is a dual-phase DC to DC Synchronous Buck Controller capable of running from commonly used 3.3 to 12V (up to 20V) voltage inputs. The device operates in current-mode for improved transient response and uses valley current sensing for enhanced noise immunity. The architecture enables accurate current sharing between interleaved phases for high current outputs. It is ideal in system applications requiring multiple output voltages. It includes a synchronization feature to eliminate beat frequencies between switching devices; provides accurate tracking capability between supplies and includes precision enable for simple, robust sequencing.
