Primechip Unveils YX2265: A High-Voltage Buck-Boost Controller for Efficient Energy Storage Solutions
Primechip has launched its new YX2265 high-voltage Buck-Boost controller, offering a cutting-edge solution for energy storage and solar power applications. Designed to address several key challenges in energy conversion, the YX2265 provides efficient constant current and constant voltage (CC/CV) control, making it ideal for battery charging and renewable energy systems.
The YX2265 controller is capable of handling input and output voltages up to 65V, making it suitable for high-voltage applications like solar panels, where open-circuit voltages can exceed 60V, and battery systems with peak voltages up to 55V. One of its standout features is its ability to operate at high frequencies (up to 3MHz), which allows for smaller inductors and a more compact system design. Additionally, it is capable of directly driving gallium nitride (GaN) power tubes, improving overall efficiency and performance.
For solar energy systems, the YX2265 excels in Maximum Power Point Tracking (MPPT) applications. The controller allows for flexible current sampling configurations, with the ability to sample both input and output currents. Real-time current monitoring through the ISMON pin helps ensure that solar panels operate at their maximum efficiency, while the ability to adjust the input average current via the ICTRL pin facilitates quick MPPT algorithm adjustments.
Primechip has designed the YX2265 to simplify system designs and reduce costs. By integrating multiple functions that would typically require separate components, the YX2265 minimizes complexity in the peripheral circuitry, resulting in lower system costs and reduced design time. Additionally, the controller offers robust protection features such as under-voltage lock-out (UVLO), soft start, and external loop compensation, ensuring reliable and safe operation across a wide range of applications.
