4. Setup and Checkup



Supply the DC/DC input power of to the terminal between VIN to PGND.



Supply the PWM controller input voltage of 5.0V to VDD terminal.



Connect the VOUT terminal to required loading device or measuring instrument. In this time, connect the EN terminal

to “L” state.

Then, turning on the EN input. Confirming the DC/DC output voltage is setting voltage.

Note:

The recommended operating conditions of MB39C502 EN pin is 5.5V maximum. Please don’t connect EN to VIN when
VIN voltage is over 5.5V.
