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 MB39C503 EN pin is 5.5V maximum. Please don’t 
connect EN to VIN when VIN voltage is over 5.5V.
