MAX1895, MAX1995 High-Efficiency, Wide Brightness Range, CCFL Backlight Controllers

The MAX1895 MAX1995 integrated controllers are optimized to drive cold-cathode fluorescent lamps (CCFL) using a synchronized full-bridge inverter architecture. Synchronized drive provides near sinusoidal waveforms over the entire input range to maximize the life of CCFLs. The controllers also operate over a wide input voltage range with high efficiency and broad dimming range.
The MAX1895 MAX1995 include safety features that limit the transformer secondary voltage and protect against single-point fault conditions including lamp-out and short-circuit faults.
The MAX1895 MAX1995 regulate the CCFL brightness in three ways: linearly controlling the lamp current, digital pulse-width modulating (DPWM) the lamp current, or using both methods simultaneously to achieve the widest dimming range (>30:1). CCFL brightness CAN be controlled with either an Analog voltage (both MAX1895 and MAX1995 or a two-wire SMBus compatible Interface MAX1895 only).
The MAX1895 MAX1995 directly drive the four external N-channel Power MOSFETs of the full-bridge inverter. An internal 5.3V linear Regulator powers the MOSFET drivers, the synchronizable DPWM Oscillator and most of the internal circuitry. The MAX1895 MAX1995 are available in the space-saving 28-pin thin QFN package and operate over the -40C to +85C temperature range.
