3 TPS62840-1YBGEVM56 Test Results
The TPS62840-1YBGEVM56 was used to take all the data in the 1.8V-6.5V, 750mA, 60nA I
Q
Step-Down
Converter data sheet. See the device data sheet for the performance of this EVM. The only difference is
the inductor used. This EVM was designed for the smallest solution size and uses a 0805-size inductor.
The data sheet inductor achieves higher efficiency but is a 0806 size and taller.
Figure 2 shows the thermal performance of the EVM.
