MAX1700 Description

They use a synchronous-rectified pulse-width-modulation (PWM) boost topology to generate 2.5V to 5.5V outputs from battery inputs such as one to three NiCd/NiMH cells or one LiIon cell. Both devices have an internal 1A, 130mΩ Nchannel MOSFET switch and a 250m Ω P-channel synchronous rectifier. With their internal synchronous rectifier, the MAX1700/ MAX1701 deliver 5% better efficiency than similar nonsynchronous...
