The MAX1774EEI+ from Analog Devices is a versatile power supply solution designed for PDAs and other handheld devices. It integrates two high-efficiency synchronous-rectified step-down converters and a boost converter for backup battery regulation.
The main converter provides an adjustable output from 1.25V to 5.5V at over 2A, while the secondary core converter delivers an adjustable voltage from 1V to 5V with up to 1.5A. Both regulators feature independent shutdown inputs and digital soft-start.
This device operates with an input voltage range of 2.7V to 28V and a switching frequency of up to 1.25MHz. It is available in a compact 28-QSOP package, suitable for surface mount applications.
The MAX1774EEI+ also includes four on-board voltage detectors to monitor AC adapter power, main battery, and backup battery status, enhancing system reliability. Automatic main battery switchover is supported when AC adapter power is removed.
