资 源 简 介
The ADP5052 combines four high performance buck regulators and one 200 mA low dropout （LDO） regulator in a 48-lead LFCSP package that meets demanding performance and board space requirements. The device enables direct connecTIon to high input voltages up to 15 V 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 1.2 A， 2.5 A， or 4 A. Combining Channel 1 and Channel 2 in a parallel configuraTIon can provide a single output with up to 8 A of current. Channel 3 and Channel 4 integrate both high-side and low-side MOSFETs to deliver output current of 1.2 A.
The switching frequency of the ADP5052 can be programmed or synchronized to an external clock. The ADP5052 contains a precision enable pin on each channel for easy power-up sequencing or adjustable UVLO threshold. The ADP5052 integrates a general-purpose LDO regulator with low quiescent current and low dropout voltage that provides up to 200 mA of output current.
