This section contains background information for the TPS61087EVM evaluation module.
This TPS61087EVM uses a TPS61087 boost converter to step up 2.5-V to 6-V input voltages to 15 V. The
goal of the EVM is to facilitate evaluation of the TPS61087 power supply solution. The EVM uses the
TPS61087 adjustable output boost converter and the appropriate feedback components to provide 15 V.
Table 1 provides a summary of the TPS61087EVM performance specifications. All specifications are given
for an ambient temperature of 25 ° C.
