One input wire, equipped with LDO and daisy-chain pins

Toshiba Corporation’s Storage/Electronic Device Solutions Company announced the release of the 'TB62D786FTG', an LED driver IC (integrated circuit) for entertainment equipment and LED lighting applications featuring nine output channels on a single input wire. Full-scale production of the 'TB62D786FTG' is scheduled to begin this coming autumn.

This new product adopts the single-wire Manchester-encoded interface commonly used in wireless communication and reduces the input signal to one.


In addition, this product is equipped with daisy-chain pins and a linear regulation circuit (LDO, 5V output) capable of a maximum input of 28V, which can improve the expandability of the LED driver unit.

In typical systems, power is supplied separately to the LED driver IC and the LED. However, using this new product, the number of wires between the microcontroller (or controller) and the LED driver unit equipped with the new driver can be reduced to four (single power supply, single-wire input, single-wire daisy-chain output, and GND), and single supply voltage operation is possible with fewer wires while maintaining a compressed, small package (VQFN24). Additionally, this product enables a reduction in the size of the LED unit board.
