Frequently Asked Questions

What input voltage range does UCC3583NG4 support and what is its nominal operating voltage?

UCC3583NG4 supports an input voltage range from 8.9 V minimum to 14 V maximum, with a nominal operating voltage of 12 V, making it compatible with standard 12 V bus architectures found in telecom and industrial power systems.

How does current-mode control in UCC3583NG4 improve power supply performance?

Current-mode PWM control in UCC3583NG4 senses the inductor current on a cycle-by-cycle basis, enabling faster transient response compared to voltage-mode control. This is especially valuable in secondary-side post-regulator designs where load steps must be handled within tight output voltage tolerances of ±5% or less.

Which package does UCC3583NG4 use and is it RoHS compliant?

UCC3583NG4 uses a 14-pin PDIP (Plastic Dual In-Line Package) through-hole package. Note that this variant carries a non-Pb-free JESD-609 e4 code, so designers should verify RoHS compliance requirements before use in restricted markets.

In which power supply topologies is UCC3583NG4 most commonly deployed?

UCC3583NG4 is most commonly used in isolated forward converters, flyback converters, and multi-output switching supplies operating from a 12 V secondary rail. Its secondary-side PWM control suits applications requiring independent post-regulation of 3.3 V, 5 V, or other regulated outputs.
