Applications

Description

The IX9907 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 IX9907 incorporates an internal 650V power

MOSFET. It has a wide voltage operating range and

low power consumption. Multiple safety features

ensure full system protection under fault conditions.

With its strong feature set and low cost, the IX9907 is

an excellent choice for quasi-resonant, off-line flyback

LED bulb designs.

The IX9907 is available in a standard 8-pin SOIC

package.
