**LTM4691IV#PBF: A High-Performance Dual 10A Step-Down µModule Regulator**

In the realm of power management, achieving high efficiency, compact form factor, and reliable performance is a constant challenge. The **LTM4691IV#PBF** from Analog Devices addresses these demands with an advanced, integrated solution. This device is a **dual 10A step-down µModule regulator** that combines power switches, inductors, and support components into a single, compact BGA package. Its innovative design simplifies the power supply design process while delivering exceptional performance for a wide range of applications, from telecommunications and data center infrastructure to industrial equipment and test & measurement systems.

A key advantage of the LTM4691IV#PBF is its **high level of integration**. By embedding the inductor, MOSFETs, DC-DC controller, and compensation network within the module, it eliminates the need for complex external component selection and layout optimization. This not only reduces the overall solution size but also accelerates time-to-market for demanding projects. The module operates over an input voltage range of **4.5V to 16V**, making it suitable for intermediate bus conversion commonly found in systems powered by 12V or 5V rails. Each channel can deliver up to 10A of continuous output current, with outputs programmable from **0.5V to 5.5V** via a single resistor.

Performance is at the core of the LTM4691's design. It boasts **peak efficiency of up to 92%**, minimizing power losses and thermal challenges in space-constrained designs. The module features a **programmable switching frequency from 500kHz to 3MHz**, allowing designers to optimize for efficiency or solution size. Furthermore, the channels can be configured to operate **180 degrees out-of-phase**, reducing input ripple current and minimizing the required input capacitance. Advanced control features include **output voltage tracking, margining, and fault protection** (over-current, over-voltage, over-temperature), ensuring safe and reliable operation under various conditions.

For thermal management, the LTM4691 is designed to efficiently transfer heat to the printed circuit board through its BGA pads. This allows the module to handle high power dissipation without requiring a heatsink, provided the PCB is designed with adequate thermal vias and copper pours.
