LCD Monitor and Display
Backlight, panel-power, and signal-protection ICs for LCD / OLED / mini-LED displays
Magnias supplies the discrete components and small-signal ICs that complete the display power tree alongside the TCON and backlight driver IC. Our portfolio covers the synchronous rectifier MOSFETs in the backlight LED string driver, ESD/TVS protection on HDMI / DP / USB-C input ports, low-noise LDOs for the panel reference rails, and Schottky diodes for the boost-stage freewheel. Same parts scale across monitor (24-32"), notebook display, tablet, and large-format signage applications.
Application areas
LCD backlight LED driver
- 60V / 100V N-Channel MOSFET (boost stage)
- Schottky (freewheel diode)
- Current-sense comparator
- Open-drain dimming PWM
Panel-power & TCON support
- High-PSRR LDO (panel reference)
- Voltage supervisor (POR / sequencing)
- Buck converter (sub-1V TCON core)
- Level shifter (TCON ↔ host CPU)
Display input protection
- ESD array (HDMI / DP / USB-C lanes)
- CMF + ESD common-mode filter
- Low-Cj ESD for high-speed lanes
- TVS on power input
OLED / mini-LED variant
- Sub-1V buck (high-current OLED core)
- 30V dual N+N MOSFET (string switching)
- Ultra-low-noise LDO (analog reference)
- Photodiode bias LDO (brightness sensor)
