High Voltage, Dimmable
LED Driver with PFC Control
Description
The IX9908 is a quasi-resonant controller optimized
for phase-cut dimmable, off-line LED applications.
Precise PWM generation supports phase-cut dimming
and power factor correction.
The product features a wide operating range, up to
600V, and low power consumption. Multiple safety
features ensure full system protection in failure
situations. The IX9908, with its strong feature set and
