Product Announcement from Marktech Optoelectronics
The TB62747 Series LED Drivers by Toshiba are ideally suited for RGB and Monochromatic LED panel displays featuring 16 driver outputs with the ability to deliver constant currents between 1.5mA and 45mA. This new series guarantees a maximum current accuracy between outputs and different devices of ± 1.5%. This ensures a constant brightness in designs built around a large number of LEDs.
The high number of outputs on the TB62747 driver, coupled with the ability to adjust the current through the use of a single external resistor, significantly reduces the number of components needed to drive LED array applications. Operation is at a supply voltage between 3.3V and 5.0V and delivers output voltages up to 26V. Control data is serial in, parallel out. The devices are fully BiCMOS-compatible and in addition, a power-on-reset (POR) facility is also available.
THE TB62747 drivers deliver fast output current response (twOE(L) = 100ns min) and, when cascaded, support serial data transfer rates of 25MHz. Multiple package options are available.
