The LTM4622A is a complete dual 2A step-down switching mode μModule® (micromodule) regulator in a tiny ultrathin 6.25mm × 6.25mm × 1.82mm LGA and 2.42mm BGA packages. Included in the package are the switching controller, power FETs, inductor and support components. Operating over an input voltage range of 3.6V to 20V, the LTM4622A supports an output voltage range of 1.5V to 12V, set by a single external resistor. Its high efficiency design delivers dual 2A continuous, 3A peak, output current. Only a few ceramic input and output capacitors are needed.

The LTM4622A supports selectable Burst Mode operation and output voltage tracking for supply rail sequencing. Its high switching frequency and current mode control enable a very fast transient response to line and load changes without sacrificing stability.

Fault protection features include input overvoltage, output overcurrent and overtemperature protection.

The LTM4622A is available with SnPb (BGA) or RoHS compliant terminal finish.

Product Detail

Demonstration circuit 2568A features the LTM4622A μModule® regulator, a tiny low profile high performance high efficiency dual step-down regulator. The LTM4622A has an operating input voltage range of 3.6V to 20V and is able to provide an output current of up to 2A for each channel. Each output’s voltage is programmable from 1.5V to 12V. The LTM4622A is a complete DC/DC point of load regulator in a low profile thermally enhanced 6.25mm × 6.25mm × 1.82mm LGA package requiring only a few input and output capacitors. Output voltage tracking is available through the TRACK/SS pin for supply rail sequencing. External clock synchronization is available through the MODE pin. For high efficiency at low load currents, the MODE pin jumper (JP3) selects the Burst Mode® option for operation in less noise sensitive applications. The LTM4622A data sheet must be read in conjunction with this demo manual for working on or modifying demo circuit 2568A.
