What are the key features of UCC3973PWG4?
- Supports supply voltages of 5 V, 9 V, 12 V, 15 V, 18 V, and 24 V
- Compact 8-pin TSSOP package for space-constrained designs
- Designed for cold-cathode fluorescent lamp (CCFL) drive circuits
- Enables efficient lamp ignition and steady-state current regulation
- Compatible with single-supply LCD backlight inverter topologies
What is UCC3973PWG4 used for?
UCC3973PWG4 is used in LCD backlight inverter circuits where CCFL lamps require controlled ignition and regulated current drive from supply rails as low as 5 V or up to 24 V. It serves display modules in industrial monitors, laptop panels, and embedded HMI systems where compact fluorescent lamp control is needed. The device also fits general-purpose fluorescent lighting control applications requiring multi-voltage compatibility in a small 8-pin package.

Frequently Asked Questions
What supply voltage options does the UCC3973PWG4 support for lamp driver circuits?
UCC3973PWG4 supports supply voltages of 5 V, 9 V, 12 V, 15 V, 18 V, and 24 V, giving designers flexibility to operate from standard system rails without additional regulation. This multi-voltage range makes it compatible with a wide variety of LCD backlight inverter and fluorescent lamp control power domains.
For a compact LCD backlight inverter design, how small is the UCC3973PWG4 footprint?
UCC3973PWG4 comes in an 8-pin TSSOP package with a body width of approximately 4.4 mm and pin pitch of 0.65 mm. This compact footprint saves significant board area compared to DIP or SOIC alternatives, making it well suited for slim panel designs in laptops, industrial monitors, and portable display modules.
Which display and lighting applications are best served by UCC3973PWG4?
UCC3973PWG4 is primarily targeted at CCFL backlight inverters in LCD panels used for laptops, industrial HMI screens, and medical display modules. It also applies to general fluorescent lamp controllers in lighting systems that can accept supply voltages anywhere between 5 V and 24 V, covering both 12 V and 24 V bus environments.
When would a designer choose UCC3973PWG4 over discrete lamp driver implementations?
Using UCC3973PWG4 reduces component count compared to discrete transistor-based CCFL drivers, integrating control logic for ignition and current regulation into a single 8-pin IC. Designs with constrained PCB space or bill-of-materials cost targets benefit from this integration, especially in consumer LCD backlighting where the multi-voltage support from 5 V to 24 V eliminates additional level-shifting components.
