Included in the package are the switching controllers, power FETs, inductors and all supporting components. Operating from an input voltage range of 4.5V to 15V, the LTM4630A supports two outputs each with an output voltage range of 0.6V to 5.3V, each set by a single external resistor. Its high efficiency design delivers up to 18A continuous current for each output. Only a few input an...
