Key Featrues
Integrated 19-mΩ and 9.4-mΩ MOSFETs - The integration of low RDS(on) MOSFETs enhances power efficiency by reducing conduction losses, making the device ideal for high-current applications up to 8 A. This also minimizes the need for external components, saving board space and simplifying design.
Selectable FSW of 400 kHz, 800 kHz, and 1.2 MHz - The ability to choose the switching frequency allows designers to optimize the converter for specific applications, balancing efficiency and component size. Higher frequencies enable the use of smaller inductors and capacitors, while lower frequencies improve efficiency in high-power scenarios.
D-CAP3™ control mode for fast transient response - This advanced control mode ensures rapid response to load changes, maintaining stable output voltage even under dynamic conditions. This is particularly beneficial for powering sensitive devices like DSPs and FPGAs, where tight voltage regulation is critical.
Selectable forced continuous conduction mode (FCCM) or Eco-mode™ - FCCM ensures low output voltage ripple, which is essential for precision applications, while Eco-mode™ maximizes efficiency at light loads. This flexibility allows the device to adapt to varying operational demands, improving overall system performance.
Pin-to-pin compatibility with 6-A to 12-A devices - The TPS568215 is compatible with other devices in the same family, such as the TPS56C215, offering scalability and design flexibility. This enables easy upgrades or downgrades in current capability without redesigning the PCB, saving time and resources.
