TPS63802EVM
1 Introduction
The Texas Instruments TPS63802 is a highly efficient, single-inductor, internally compensated, buck-boost
converter in a 10-pin, 3-mm × 2-mm HotRod QFN package.
1.1 Background
The TPS63802EVM uses the TPS63802 integrated circuit (IC) and is set to a 3.3 V output and operates
with an input voltage between 1.3 V and 5.5 V.
1.2 Performance Specification
Table 1 provides a summary of the TPS63802EVM performance specifications. All specifications are given
for an ambient temperature of 25°C.

1.3 Modifications
The printed-circuit board (PCB) for this EVM is designed to accommodate the TPS63802. Extra positions
are available for additional input and output capacitor and feed forward capacitor.
1.3.1 IC U1 Operation
U1 is configured for evaluation of the adjustable-output version. This EVM is set to 3.3 V. Resistors R1
and R2 can be used to set the output voltage between 1.8 V and 5 V. See the datasheet for
recommended values.
