Analog Devices LTM4626 and LTM4638 Step-Down ┬ÁModule Regulators are complete step-down DC-DC switching mode power regulators in a tiny 6.25mm x 6.25mm BGA package. Included in the ┬ÁModulepackage are the switching controller, inductor, power FETs, and support components. Operating over an input voltage range of 3.1V to 20.0V, the devices support an output voltage range of 0.6V to 5.5V, set by a single external resistor. The devices produce a continuous output current of up to 12A (LTM4626) and 15A (LTM4638). Only bulk input and output capacitors are required.

The ┬ÁModules support selectable discontinuous mode operation and output voltage tracking for supply rail sequencing. The high switching frequency and current mode control features of these devices allow a very fast transient response to line and load changes without sacrificing stability.

Fault protection features include overcurrent, overvoltage, and overtemperature protection. Integrated heat sink inductors add further thermal protection.

Typical applications include telecom, datacom, networking, and industrial equipment; medical diagnostic equipment; data storage rack units and cards; and test and debug systems.
