Product Overview

The MAX1775EEE+T from Maxim Integrated Products is a dual-output step down DC to DC converter in 16 pin QSOP package. The MAX1775 dual, step down DC to DC converter generates both the main (+3.3V at over 2A) and core (+1.8V at up to 1.5A) supplies for a complete power solution for PDAs, subnotebooks and other hand-held devices. The main output is adjustable from +1.25V to +5.5V. The core output is adjustable from 1V to 5V. Both switching converters operate at up to 1.25MHz for small external components and use synchronous rectifiers to achieve efficiencies up to 95%. Operation with up to 100% duty cycle provides the lowest possible dropout voltage to extend useful battery life. The MAX1775 accepts inputs from +2.7V up to +28V, allowing use with many popular battery configurations as well as AC to DC wall adapters.
  • 170µA quiescent current
  • 5µA shutdown current

  • Independent shutdown inputs
  • Operating temperature range from -40°C to +85°C
