AP34063(Boost) Application Information and Demo Board User Guide
1. Description
The AP34063(Boost) evaluation modules (EVM) provide a means for the user to evaluate quickly the
functionality and electrical performance of the AP34063 device. All inputs and outputs are brought out to
test points for control and monitoring. All passive components are included on the EVM for device
operation. The input pin should be connected to an external supply; the output should be connected to a
load.
