Industry Smallest And Low Profile 6.5w 2.0a Dc/dc Buck Converter With High Output Power Density - Vishay Siliconix

The DC/DC converter FX5545G105 is a programmable topology synchronized Buck converter for todays continuous changing portable electronic market. The DC/DC converter provides flexibility of utilizing various battery configurations and chemistries such as NiCd, NiMH, or Li+ with an input voltage range of 2.7V to 6V. An additional flexibility is provided with topology programmability to power multiple loads such as power Amplifiers Microcontrollers or baseband Logic ICs. For ultra-high efficiency, converters are designed to operate in synchronous rectified PWM mode under full load while transforming into externally controlled pulse-skipping mode (PSM) under light load.
