Description
The TPS6286x devices are high-frequency synchronous step-down converters with I2C- and VSEL-Interface. They provide an efficient, flexible, and high-power density point-of-load DC/DC solution. At medium to heavy loads, the converter operates in PWM mode and automatically enters Power Save Mode operation at light load to maintain high efficiency over the entire load current range. The device can also be forced in PWM mode operation for the smallest output voltage ripple. Together, with its DCS-control architecture, excellent load transient performance and tight output voltage accuracy are achieved. With the I2C interface and a dedicated VSEL pin, the output voltage is quickly adjusted to adapt the power consumption of the load to the ever-changing performance needs of the application. The TPS6286x family is available with two VSEL pins and four factory preset voltages to allow usage without I2C interface.
Drop-in replacement with upgraded functionality to the compared device.
Same functionality with different pin-out to the compared device.
