ADP5050ACPZ-R7

ADP5050 is a combines four high performance buck regulators and one 200mA low dropout (LDO) regulator that meets demanding performance and board space requirements. The device enables direct connection to high input voltages up to 15V with no preregulators. Channel 1 and Channel 2 integrate high-side power MOSFETs and low-side MOSFET drivers. Combining Channel 1 and Channel 2 in a parallel configuration can provide a single output with up to 8A of current. Channel 3 and Channel 4 integrate both high-side and low-side MOSFETs to deliver output current of 1.2A. The switching frequency of the ADP5050 can be programmed or synchronized to an external clock. This contains a precision enable pin on each channel for easy power-up sequencing or adjustable UVLO threshold. Application includes small cell base stations, FPGA and processor applications, security and surveillance, medical applications.
