2 BACKGROUND

The TPS65282 PMIC contains a buck converter and two power switches. The buck converter is designed to provide an adjustable voltage with maximum 4-A continuous currents. The two power switches are designed to provide current limit at 75 mA - 2.7 A, while the current limit is available setting by external resistor.

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 V
fSW = 600 kHz
(25°C ambient)		Buck : 5.0 V, up to 4 A
Power Switch 1: 5.0 V, up to 2.7 A
Power Switch 2: 5.0 V, up to 2.7 A

The evaluation module is designed to provide access to the features of the TPS65282. 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.
