Analog Devices / Maxim Integrated MAX25254 8A Synchronous Buck Converters

Analog Devices MAX25254 8A Synchronous Buck Converters are integrated high-side and low-side switches. The ICs deliver up to 8A per channel with input voltages from 3V to 36V. These Analog Devices converters use only 12μA quiescent current at no load. Voltage quality can be monitored by observing the PGOOD signals.
