The ADP5052-EVALZ is an evaluation board for evaluating ADP5052 five channel integrated power solution with buck and LDO regulator. The ADP5052 combines four high performance buck regulators and one 200mA low dropout (LDO) regulator in a 48 lead LFCSP package that meets demanding performance and board space requirements. The ADP5052 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. 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 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 ADP5052 can be programmed or synchronized to an external clock.
