Analog Devices LTM4626 and LTM4638 µModule buck regulators

Analog Devices LTM4626 and LTM4638 µModule regulators offer a 12 or 15 A (respectively) step-down DC/DC regulator solution that incorporates a switching controller, power FETs, inductor and support components in a 6.25 mm² BGA package. Operating over an input voltage range of 3.1 to 20 V, both devices support an output voltage range of 0.6 to 5.5 V, set by a single external resistor.

The regulators support selectable discontinuous mode operation and output voltage tracking for supply rail sequencing. The devices’ high switching frequency and current mode control enable a fast transient response to line and load changes without sacrificing stability. Additionally, the regulators include overvoltage, overcurrent and overtemperature protection.

The step-down switching mode regulators are designed to reduce solution size and deliver good power circuit performance in applications such as telecom, networking, industrial equipment, medical diagnostic equipment, data storage, and test and debug systems.
