- Built-in LDO and daisy-chain pins realize downsizing of LED modules
TOKYO — (BUSINESS WIRE) — June 30, 2016 — Toshiba Corporation's (TOKYO: 6502) Storage & Electronic Devices Solutions Company today announced the launch of “TB62D786FTG”, a new LED driver IC with single-wire input and 9-channel output, for amusement equipment and LED illumination applications. Full-scale production is scheduled to start this autumn.

The new product adopts a single-wire Manchester-encoded interface, which is generally used for wireless communications, and the number of input signals is reduced to one. In addition, built-in daisy-chain pins and a linear regulation circuit (LDO, 5V output) with up to 28V input improve the extendibility of the LED driver unit.
In a typical system, power supply has to be supplied to LED driver ICs and LEDs separately. Using the new product, the number of wires between a microcontroller (or a controller) and an LED driver unit mounting the new driver can be reduced to four wires (single power supply, single-wire input, single-wire daisy-chain output, and GND), and a single supply voltage operation unit with less wiring can be created with a compact package (VQFN24). This also allows the size of the LED unit board to be downsized.
