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.
