TPS61291EVM-569 Evaluation Module
The TPS61291EVM-569 (PWR569-001) facilitates the evaluation of the TPS61291 Low I_Q Boost
Converter with Bypass Mode device. The device outputs a user-selectable output voltage of 2.5 V, 3 V, or
3.3 V. Available output current depends on the input voltage and output voltage but is generally around
200 mA for most applications.
