Linear Technology's LTM4676IY: The High-Efficiency, Dual 13A or Single 26A μModule Regulator

The LTM4676IY is a state-of-the-art, high-efficiency, dual 13A or single 26A, DC/DC step-down power module regulator from Linear Technology. It is housed in a compact, over-molded Land Grid Array (LGA) package measuring 16mm x 16mm x 5.01mm, designed to operate over a wide input voltage range from 4.5V to 17V. This powerful solution is engineered for optimal thermal performance and is suitable for a variety of applications, including telecom/datacom systems, distributed power architectures, and industrial equipment.

Advanced Features and Performance

The LTM4676IY is equipped with an array of advanced features that set it apart from traditional power regulators. It incorporates dual DC/DC controllers, power switches, inductors, and support components, all within its compact LGA package. The module can be configured to provide two independent 13A outputs or a single 26A output, offering flexibility for different power requirements.

With its high efficiency design, the LTM4676IY can deliver full 26A continuously up to 85°C ambient without airflow or 200LFM airflow up to 70°C ambient with derating. This exceptional thermal performance ensures reliability and longevity even in demanding environments.

Intelligent Power Management

One of the key advantages of the LTM4676IY is its integrated digital power system management (PSM) capability. This allows users to monitor vital parameters such as voltage, current, temperature, and power. Additionally, it provides programmable control and protection features through the PMBus interface. The device's advanced digital telemetry and control simplify system development and enable real-time system optimization.

Robust Protection and Reliability

The LTM4676IY is designed with robust protection features that ensure safe and reliable operation under a variety of conditions. It includes overvoltage, overcurrent, and overtemperature protection, safeguarding both the power module and downstream components from potential damage.

In summary, the LTM4676IY from Linear Technology is a versatile, high-performance power solution that combines efficiency, flexibility, and advanced management features in a compact package. It is an ideal choice for designers looking to optimize power systems in space-constrained and thermally challenging applications.
