nn 9mm × 11.25mm × 4.92mm BGA Package The LTM®4642 is a complete dual 4A or single 8A step-down
DC/DC μModule® (micromodule) regulator. Included in the
package are the switching controller, power FETs, inductor,
and all support components. Operating over input voltage
ranges of 4.5V to 20V, (2.375V min with external CPWR
bias), the LTM4642 supports two outputs with voltage
ranges of 0.6V to 5.5V, set by a single external resistor.
Its high efficiency design delivers 4A continuous current …
