Measurement setup
The enable switch has three states (ON, OFF and Open).
1. When it is toggled to “ON” side, the device starts operation.
2. When it is toggled to “OFF” side, the device stop operation and keep shut down status.
3. When it is set to open, the EN pin floats and an external voltage can be applied to the EN terminal pin on the
EVB. If you don’t apply an external voltage to EN pin, the enable switch should not to be set to the middle
position.
The mode switch has three states (PWM, PFM/PWM and Open).
1. When it is toggled to “PWM” side, the device operates PWM forced mode.
2. When it is toggled to “PFM/PWM” side, the device operates PFM/PWM automatic mode.
(LXDC2UR25G-308 and LXDC2UR25G-312 forced PFM mode)
3. When it is set to open, the mode pin floats and an external voltage can be applied to the Mode terminal pin on
the EVB. If you don’t apply an external voltage to Mode pin, the mode switch should not to be set to the
middle position.
