Texas Instruments' TPS62865 and TPS62867 step-down converters are designed to provide an efficient, flexible, and high power density solution for various applications. With an input range of 2.4 V to 5.5 V, these converters utilize DCS-control™ technology to achieve excellent load transient performance and tight output voltage accuracy.
At medium to heavy loads, these converters operate in PWM mode, ensuring optimal performance. Furthermore, they automatically enter power-save-mode operation at light-load, allowing them to maintain high efficiency over the load current range. Additionally, the converters can be forced into PWM mode operation to minimize output voltage ripple, providing enhanced flexibility in their operation.
These devices also feature a power-good signal and an internal soft-start circuit, contributing to their reliable and efficient performance. Moreover, the converters can operate in 100% mode, further enhancing their versatility in various applications.
In terms of protection features, the devices incorporate a HICCUP short-circuit protection mechanism and thermal shutdown, ensuring reliable operation and safeguarding against potential faults. These comprehensive protection measures contribute to the overall reliability and robustness of the TPS62865 and TPS62867 converters.
In summary, Texas Instruments' TPS62865 and TPS62867 step-down converters, with their utilization of DCS-control™ technology, offer a compelling combination of fast transient response, high efficiency, and robust fault protection, making them ideal choices for a wide range of power management applications.
