How to Choose an LED Driver IC (Fine-Pitch, Rental, Broadcast)
Choosing a driver IC comes down to matching five things to your application: drive type (sink/source), channel count, scan rate, grayscale/refresh needs, and — critically — what your NovaStar receiving card and firmware actually support. Here is how to narrow it down.
Match the application
- Fine-pitch indoor / broadcast: an S-PWM part with embedded SRAM and strong low-gray performance — MBI5153, ICND2153, ICND2055.
- High pixel density / high scan: a high-scan part like ICND2163 or ICND2065.
- Energy-sensitive / large installs: a common-cathode (source) driver — see common cathode vs anode.
- Outdoor / simple signage: conventional PWM can be sufficient.
Then confirm NovaStar support
This is where most projects trip up. The same IC may be supported on one card but need a specific firmware version on another. Every driver IC page lists the exact NovaStar receiving cards and firmware versions that drive it, with download links. Already have a panel? Upload your .rcfgx and we'll tell you the IC, scan, grayscale and the right firmware. Or call our team at 321-747-3220.
FAQ
What’s the most important factor in choosing a driver IC?
Matching the IC to your module’s drive type and your NovaStar card/firmware support. After that, scan rate, grayscale/refresh (S-PWM vs PWM), and channel count refine the choice.
Can Olympian LED help me pick?
Yes — upload your config to the RCFGX viewer or call 321-747-3220. As a USA NovaStar distributor we can match the driver IC, receiving card, and firmware to your build.
