Products for LCDs
ROHM offers MOSFETs specifically designed for LED backlights, which are quickly becoming the preferred choice over CCFL(EEFL) due to their smaller environmental footprint. All required functions are integrated, including a step-up converter and load switch circuit that provides a VDSS optimized for LED backlights (45V/60V). In addition, the industry's lowest ON-resistance results in significantly lower power consumption.
ROHM's inverter control ICs utilize a high precision frequency design for greater efficiency. A wide range (0% - 100%) burst light adjustment function and low noise analog light adjustment mode make mixed light adjustment possible. In addition, the output can be completely turned OFF, contributing to greater energy savings and longer life.

Low 1.5V drive voltage LCD Timing Control ICs
BU90A□□ / B□□-□□series
The industry's most advanced (0.13µm) process was used to achieve an ultra-low internal drive voltage of 1.5V - ideal for a wide range of devices, from notebook computers to conventional monitors.
ROHM' s high voltage resistance constant current drivers feature high current handling capability, highly efficient operation (85%+), and allow individual control of the brightness at each of the 8 built-in channels. The result is optimized contrast and visibility with reduced power consumption
A newly developed LCD drive voltage generator circuit isbuilt in, drastically reducing power consumption. In addition, the specialized design eliminates the need for external components, making display possible via 3-line connection to a microcontroller.
A lower internal resistance lessens the amount of heat generated, reducing power loss, while a current handling capability of 4A makes it possible to use large current circuits in the vicinity of the power supply. These optimized features make ROHM filters highly suited for noise countermeasures on IC power supply lines and in video equipment.
