11. Measurement Data
Micro DC-DC Converter evaluation board (P2LX1568F)
Measurement setup
* Evaluation board initial output Voltage setting : 3.3V ( resistor : 560Ω + 16Ω )
The enable switch has three positions.
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 middle of “ON” and “OFF”, the EN pin becomes floated and can be applied an external
voltage through the EN terminal pin on the EVB. If you don’t apply external voltage to EN pin, the enable
switch should not to be set to the middle position.
