DESCRIPTION
The LTM®4618 is a complete 6A output switching mode DC/DC power supply in a 9mm × 15mm × 4.32mm LGA package. Included in the package are the switching controller, power FETs, inductor and all support components. Operating over an input voltage range of 4.5V to 26.5V, the LTM4618 supports an output voltage range of 0.8V to 5V set by a single external resistor. Its high effi ciency design delivers 6A continuous current (8A peak). Only a few input and output capacitors are needed.
