Description

General part information

TPS65279V Series

The TPS65279V is a monolithic dual synchronous buck regulator with wide 4.5-V to 18-V operating input voltage that can operate in 5-, 9-, 12- or 15-V bus voltages and battery chemistries. The converters are designed to simplify its application while giving the designer the option to optimize their usage according to the target application.

Each buck converter in TPS65279V has external feedback resistors that can be used for setting the initial start up voltage. The feedback voltage reference for this start-up option is 0.6 V. Once the VID DAC is updated via the I2C, the buck converter switches feedback resistors from external to internal. The output voltage in each buck can be programmable from 0.68 V to 1.95 V in 10-mV steps with I2C Controlled 7-Bits VID.

Each buck converter in TPS65279V can also be I2C controlled for enabling/disabling output voltage, setting the pulse skipping mode and reading the power good status and die temperature warning.
