Background

The TPS62125EVM-044 (PWR044) uses the TPS62125 device and is set to a 3.3-V output. The EVM operates with full-rated performance with an input voltage between 4V and 17 V, assuming JP1 is connected between ON and EN.

The TPS62125 device contains an adjustable enable threshold and adjustable hysteresis feature. Thus, the input voltage at which the device enables and disables is fully programmable by the user. In the TPS62125EVM-044, the device is set to turn on at 6 V and turn off at 4 V. This feature can be bypassed by using jumper JP1, which overrides the programmed threshold voltages.
