Features

AI Translation
  • Full-bridge resonant inverter architecture optimized for CCFL driving
  • Resonant operation maximizes strike capability and delivers near-sinusoidal waveform across full input range to extend CCFL lifetime
  • Wide input voltage range (4.6V to 28V) with high power-to-light efficiency
  • Safety features protecting against multiple single-point fault conditions, including lamp extinction and short-circuit faults
  • 10:1 dimming range via DPWM method
  • DPWM frequency precisely adjustable via resistor or synchronizable to external signal
  • Brightness controlled by analog voltage on CNTL pin
  • Direct drive for four external n-channel power MOSFETs in full-bridge inverter
  • Internal 5.3V linear regulator powering MOSFET drivers, DPWM oscillator, and most internal circuitry
  • Low-cost 24-pin QSOP package
  • Operating temperature range: -40°C to +85°C
  • Synchronization to resonant frequency for extended lamp lifetime
  • Input voltage feedforward with excellent line rejection
  • Precise dimming control with analog interface
  • Adjustable precise DPWM frequency with synchronization capability
  • Adjustable lamp current rise and fall times
  • Secondary voltage limiting to reduce transformer stress
  • Lamp extinction protection with adjustable timeout
  • Secondary overcurrent protection with adjustable timeout
