AP1609 Application Information and Demo Board User Guide
1. Description
The AP1609(Boost) evaluation modules (EVM) provide a means for the user to
evaluate quickly the functionality and electrical performance of the AP1609 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.
