Product Overview: LTM4620IY#PBF

The LTM4620IY#PBF is a high-performance dual 13A or single 26A step-down µModule (micromodule) regulator from Linear Technology, now part of Analog Devices. This compact and versatile power management solution is designed to meet the rigorous requirements of applications requiring a low voltage, high current output, and a small footprint.

Featuring a wide input voltage range from 4.5V to 16V, the LTM4620IY#PBF is capable of delivering up to 26A of continuous output current with dual outputs that can supply 13A each. The outputs are adjustable with a range of 0.6V to 2.5V, which can be set by a single external resistor. This flexibility makes it suitable for a variety of uses, including point-of-load applications, telecommunications, data processing, and storage systems.

The LTM4620IY#PBF incorporates Linear Technology's advanced packaging technology, which enables an efficient heat dissipation and a high level of integration. The µModule regulator includes the switching controller, power FETs, inductors, and all support components, all housed within a compact (15mm x 15mm x 5.01mm) LGA package. This level of integration simplifies the design process, reduces external component count, and minimizes the PCB footprint.

Key features of the LTM4620IY#PBF include high efficiency, fast transient response, and precise regulation. Additionally, it offers multiple protection features such as overvoltage, overcurrent, and over-temperature protection, ensuring reliable operation under a variety of conditions. The device also supports frequency synchronization, output voltage tracking, and has a power good indicator for ease of power sequence and monitoring.

For applications requiring a robust power solution that can operate in harsh environments, the LTM4620IY#PBF is specified for operation from -40°C to 125°C, making it an ideal choice for industrial and military applications where temperature extremes are common.

In conclusion, the LTM4620IY#PBF from Linear Technology is a powerful, efficient, and highly integrated step-down regulator, perfect for designers looking to maximize performance in a limited space while ensuring reliability and ease of use.
