LTC3623 is a ±5A high efficiency, current mode synchronous buck regulator that is adjustable from 14.5V down to 0V output with a single resistor. Its architecture uses a 50 µA current reference, combined with a single resistor, to set the output voltage. by Graham Prophet @ edn-europe.com
The LTC3623’s 4V to 15V input voltage range is suitable for dual-cell Li-Ion applications, and fixed 5V and 12V intermediate bus systems. Low R DS(ON) integrated N-channel power MOSFETs (60mΩ top & 30 mΩ bottom) and synchronous rectification deliver efficiencies up to 96%. The device’s design allows dynamic adjustment of output voltage from 0V to V IN – 0.5V, offering virtually rail-to-rail performance.
