ADP5053ACPZ-R7

ADP5053 is an integrated power solution. It combines four high performance buck regulator, a supervisory circuit, a watchdog timer, and a manual reset that meets demanding performance and board space requirements. This device enables direct connection to high input voltages upto 15V with no preregulators. Channel 1 and channel 2 integrate high-side power MOSFET and low-side MOSFET drivers. External NFETs can be used in low-side power devices to achieve an efficiency optimized solution and deliver a programmable output current of 1.2A, 2.5A, or 4A. Combining channel 1 and channel 2 in a parallel configuration can provide a single output with upto 8A of current. It is used in applications such as small cell base stations, FPGA and processor applications, security and surveillance, medical applications.
