ADP5054 - Analog Devices

ADP5054 Quad Buck Regulator Integrated Power Solution

The ADP5054 combines four high performance buck regulators in a 48-lead LFCSP package that meets demanding performance and board space requirements. The device enables direct connection to high input voltages of up to 15.5 V with no preregulators. Channel 1 and Channel 2 integrate high-side power metal-oxide semiconductor field effect transistors (MOSFETs .
