ADP5052 - Analog Devices

ADP5052 5-Channel Integrated Power Solution

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 MOS.
