Linear Technology's LTM4620AEY#PBF - Dual 13A or Single 26A DC/DC µModule Regulator

The LTM4620AEY#PBF is a high-performance dual 13A or single 26A step-down DC/DC µModule (micromodule) regulator from Linear Technology that combines top-notch power management capabilities in a compact, encapsulated package. This product is designed to meet the needs of demanding applications requiring high power density and efficient heat dissipation, such as telecommunications, datacom infrastructure, and advanced computing systems.

Featuring a wide input voltage range from 4.5V to 16V and an output voltage range from 0.6V to 5.5V, the LTM4620AEY#PBF is versatile enough to handle a variety of power supply configurations. This flexibility is further enhanced by the module's ability to operate as two single 13A outputs or be configured to provide a single 26A output, providing solutions for both isolated and non-isolated applications.

The LTM4620AEY#PBF utilizes advanced packaging technology to encapsulate its high-performance switching controller, power FETs, inductors, and all the supporting components within a compact (15mm x 15mm x 4.41mm) over-molded LGA package. This integration simplifies the design process, reduces external component count, and results in a quicker time-to-market for complex power systems.

Efficiency is a key feature of the LTM4620AEY#PBF, with its high switching frequency and phase-lockable frequency (250kHz to 780kHz) minimizing the size of external components and enabling the use of low ESR ceramic capacitors. Additionally, the module offers precision output voltage tracking, making it ideal for supply rail sequencing in sensitive systems.

Protection features are also built into the LTM4620AEY#PBF, including overvoltage, overcurrent, and over-temperature protection, ensuring reliable operation under a variety of conditions. The device also supports external synchronization, which helps in reducing noise and interference when multiple devices are used in parallel.

With its robust feature set, the LTM4620AEY#PBF exemplifies Linear Technology's commitment to delivering high-performance power management solutions that cater to the evolving needs of modern electronics.
