**LT8364EDE#PBF: A Comprehensive Technical Overview and Application Guide for the 60V, 2A Synchronous Boost/SEPIC/Inverting Converter**

The **LT8364EDE#PBF** from Analog Devices is a versatile, high-performance monolithic switching regulator that excels in a wide range of DC-DC conversion topologies. This IC integrates **two internal 60V, 2A N-channel MOSFET switches**, eliminating the need for external Schottky diodes and significantly enhancing efficiency and reducing solution size. Its ability to operate in **boost, SEPIC, and inverting configurations** makes it an ideal choice for complex industrial, automotive, and telecommunications power systems where input voltages can vary widely above or below the regulated output.

A key strength of the LT8364 is its **wide input voltage range of 2.8V to 60V**. This allows it to handle high voltage transients commonly found in automotive and industrial environments with ease, ensuring robust and reliable operation. The device can generate output voltages of up to 60V in boost mode and negative voltages down to -40V in inverting mode, providing designers with exceptional flexibility.

The internal synchronous rectification is a major contributor to the IC's high efficiency, which can **exceed 90%** across a broad load range. This feature is crucial for battery-powered applications and systems where thermal management is a concern. The switching frequency is user-programmable from **200kHz to 2MHz** via a single resistor, allowing designers to optimize the trade-off between efficiency and the size of external passive components. Furthermore, the high switching frequency capability enables the use of smaller inductors and capacitors, leading to more compact power supply footprints.

For noise-sensitive applications, the LT8364 offers a **synchronization pin (SYNC)** that allows the internal oscillator to be synced to an external clock, preventing beat frequencies in systems with multiple switching regulators. Additional features include programmable soft-start for controlled in-rush current, a power good flag for system sequencing, and frequency foldback for stable operation during short-circuit conditions.

**Typical applications** are diverse, including:

* **Automotive Systems:** Powering infotainment, ADAS, and instrumentation from a fluctuating 12V battery rail.

* **Industrial Control:** Generating intermediate bias rails (e.g., ±12V, 24V) from a 4-20mA loop or a central 5V/12V bus.

* **Telecom Infrastructure:** Converting a -48V backplane to a lower positive voltage for line cards.

* **Medical Equipment:** Creating isolated bias supplies or specific positive/negative voltage rails for analog sensors and amplifiers.

When designing with the LT8364, careful attention must be paid to the PCB layout. A proper layout with a small, tight switching loop, a solid ground plane, and direct connections for feedback resistors is critical for achieving stable performance and low EMI.
