Frequently Asked Questions
What kind of input voltage does the PT6980 series require?
It operates from a 12-V input bus.
How is output power provided when configuring the modules?
The module provides two independently regulated outputs (V o and V l) that can simultaneously power various components, such as DSP cores.
Are there protection features built into the regulator?
Yes, the features include output current limit and short-circuit protection.
What capacitors are required for proper PT6980 operation?
A 330µF electrolytic capacitor is required at both the input and output (or 300µF for Oscon®/low ESR tantalum).
What is the typical switching frequency range?
The typical switching frequency ranges from 500 kHz to 600 kHz when operating across the full voltage range.
