TB62779FNG TOSHIBA Bi-CMOS Integrated Circuit Silicon Monolithic
TB62779FNG 9-Channel Constant-Current LED Driver of the 3.3-V and 5-V Power Supply Voltage Operation
The TB62779FNG is a constant-current driver designed for LED and
LED display lighting.
The TB62779FNG incorporates nine channels of seven-bit PWM
dimming controllers and constant-current drivers. Nine constant-current
drivers are divided into three blocks, each consisting of three drivers, and
the output current of each can be independently adjusted by the relevant
external resistor.
The TB62779FNG is controlled using the DATA and CLK input signals.
Up to 64 slave IDs (slave addresses) can be independently assigned to the
TB62779FNG.
Fabricated using the Bi-CMOS process, the TB62779FNG is capable of
high-speed data transfers.
The TB62779FNG operates with a supply voltage of 3.3 V or 5 V.
The TB62779FNG is RoHS (2002/95/EL) compliant.
