Aimed at systems requiring multiple low-voltage supplies, Linear Technology’s LTC3374A can be configured to supply two to eight independent regulated outputs with 15 possible output-current configurations. Each of the eight synchronous 1-A buck converters is powered from an independent 2.25-V to 5.5-V input supply. Output voltage range is 0.8 V to VIN. by Susan Nordyk @ edn.com
The LTC3374A is well-suited for a variety of multichannel applications, including industrial, automotive, and communication systems. Along with a peak efficiency of 94%, the device provides one output with ±1% voltage accuracy and up to seven additional outputs with ±2% accuracy. Up to four adjacent buck regulators can be combined in parallel to provide up to 4 A of output current with a single shared inductor by connecting their VIN pins together, their SW pins together, and by connecting the slave bucks’ FB pins to the input supply.
