• Manufacturer Part Number: PS10NG-G-M905
• Description: Quad Power Sequencing Controller
• Manufacturer: Supertex

PWRGD Output Configuration
The PS10 open drain power good outputs can be connected directly to the Enable pins of the DC/DC converter. The
internal pull-up and clamp of the DC/DC converter sets the logic High Enable/Disable voltage.
Opto-isolated Enable
Some applications require opto-isolator interface to the Enable pin of the DC/DC converter.
