2 Background

The TPS65279V PMIC is designed to provide dual 5 A of continuous currents with an operational range of 4.5 to 18 V. The TPS65279V features I2C controlled voltage identification (VID) and the output voltage can be set by I2C from 0.68 V to 1.95 V. Without I2C, voltage can also be programmed by an external resistor divider. The TPS65279V features externally programmed switching frequency ranging from 200 kHz to 1.6 MHz, external compensation, soft-start and enable.

As there are many possible options to set the converters, Table 2-1 presents the performance specification summary for the EVM.

Table 2-1 Summary of Performance
Test ConditionsPerformance
Vin = 4.5 V to 18 VBuck1 : 1.0 V, up to 5 A, VID control
fsw = 500 kHz (25°C ambient)Buck2 : 1.1 V, up to 5 A, VID control

The EVM is designed to provide access to the features of the TPS65279V. Some modifications can be made to this module to test performance at different input and output voltages, current and switching frequency. Please contact TI Field Applications Group for advice on these matters.
