Frequently Asked Questions
How can I compensate for voltage drop?
Use the 'Vo Sense' input, which allows the regulation circuit to compensate for voltage drop between the module and the load.
What types of systems are this power module suitable for powering?
It is designed for complex multi-processor digital systems, DSPs, micro-processors and bus drivers.
How does the Auto-Track™ feature work?
Auto-Track™ Sequencing simplifies dynamic startup in power systems by ensuring sequential tracking of voltages during power up and down cycles.
What should I do if I don't use the Inhibit pin?
If unused, this input should be connected to V. If left open-circuit, it will produce an output when the voltage rises.
