High-Efficiency, Wide Brightness  
Range, CCFL Backlight Controllers  
General Description  
Features  
The MAX1895/MAX1995 integrated controllers are opti-  
mized to drive cold-cathode fluorescent lamps (CCFL)  
using a synchronized full-bridge inverter architecture.  
Synchronized drive provides near sinusoidal wave-  
forms 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.  
o Synchronized-to-Resonant Frequency  
Good Crest Factor for Longer Lamp Life  
Ensures Maximum Strike Capability  
o High Power to Light Efficiency  
o Wide Dimming Range (3 Methods)  
Lamp Current Adjust: >3 to 1  
Digital PWM (DPWM): >10 to 1  
Combined: >30 to 1  
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.  
o Feed-Forward for Fast Response to Step Change  
of Input Voltage  
o Wide Input Voltage Range (4.6V to 28V)  
The MAX1895/MAX1995 regulate the CCFL brightness  
in three ways: linearly controlling the lamp current, digi-  
tal 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™ com-  
patible interface (MAX1895 only).  
o Transformer Secondary Voltage Limiting to  
Reduce Transformer Stress  
o Lamp-Out Protection with 2s Timeout  
o Short-Circuit and Other Single-Point Fault  
Protections  
o Synchronizable DPWM Frequency  
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 -40°C to +85°C temperature  
range.  
o Dual-Mode Brightness Control Interface  
SMBus Serial Interface (MAX1895 Only)  
Analog Interface (Both Devices)  
o High-Accuracy Analog Interface  
Separate 100% Brightness Voltage Reference  
Pin (CRFSDA)  
Separate Minimum Lamp-Current Set-Point Pin  
(MINDAC)
