Key Featrues
PolyPhase® Operation: This feature reduces the required input and output capacitance, lowering power supply-induced noise. It also allows the use of smaller inductors compared to single-phase designs, enhancing efficiency and reducing component size and cost in high-power applications.
Synchronous Rectification: By incorporating synchronous rectification, the LTC3784 achieves higher efficiency and reduces power losses. This minimizes heat dissipation, simplifying thermal management and making it suitable for compact, high-performance designs.
Wide Input Voltage Range (4.5V to 60V): The controller operates across a broad input voltage range, enabling it to handle diverse power sources. It can also operate down to 2.3V after start-up, making it versatile for applications with varying input conditions.
High Output Voltage (Up to 60V): The LTC3784 supports output voltages up to 60V, making it ideal for applications requiring high voltage levels, such as industrial, automotive, and medical systems.
Current Sensing Options (RSENSE or Inductor DCR): This feature provides flexibility in current sensing, allowing designers to choose between external resistor sensing or inductor DCR sensing. This adaptability optimizes performance and reduces external component count, improving overall system efficiency.
