TPS628680ARQYR

The TPS62868 and TPS62869 devices are high-frequency synchronous step-down converters with an I2C interface, which can provide efficient, adaptive, and high-power density solutions. The converter operates in PWM mode under medium to high load conditions and automatically enters the power-saving mode at light loads, thus maintaining high efficiency across the entire load current range. The device can also be forced to operate in PWM mode to achieve minimum output voltage ripple. With their DCS-Control architecture, these devices can achieve excellent load transient performance and meet strict output voltage accuracy requirements. Through the I2C interface and dedicated VID pins, the output voltage can be quickly adjusted to adapt the power consumption of the load to the changing performance requirements of relevant applications.
