IX9907 - LED Driver

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.

Features

  • Internal 650V, 2 power MOSFET.
  • Single stage, primary control with PFC and dimming features.
  • >90% efficiency.
  • Power factor >98%.
  • Wide operating voltage range.
  • Digital soft-start.
  • Foldback correction and cycle-by-cycle peak current control.
  • Output over-current and over-voltage protection.
  • Over-temperature protection.
  • Under-voltage lockout.
