8-Channel Constant-Current LED Driver of the 3.3-V and 5-V Power Supply Voltage
Operation
The TB62777FNG/FG is comprised of constant-current drivers
designed for LEDs and LED panel displays.
The regulated current sources are designed to provide a
constant current, which is adjustable through one external
resistor.
The TB62777FNG/FG incorporates eight channels of shift
registers, latches, AND gates and constant-current outputs.
Fabricated using the Bi-CMOS process, the TB62777FNG/FG is
capable of high-speed data transfers.
The TB62777FNG/FG is RoHS.
