Toshiba Supports Downsizing of LED Modules with Single-Wire Input Illumination LED Driver
Toshiba Electronics Europe has introduced a 9-channel output LED driver IC that will save board space and reduce the size of LED modules in a variety of lighting and illumination applications.
The TB62D786FTG has a single-wire Manchester-encoded interface, which is often used for wireless communication. Built-in daisy-chain pins and a linear regulation circuit (LDO, 5V output) capable of handling inputs from 7 V to 28 V improve the extendibility of the IC.
In conventional designs, power has to be supplied to the LED driver ICs and LEDs separately. Using the TB62D786FTG, the number of wires between a host controller or MCU and the LED driver unit can be reduced to just four: a single power supply, single-wire input, single-wire daisy-chain output, and GND. Fewer connections, combined with the IC’s compact VQFN24A package, allows overall size of the LED unit board to be reduced and the IC to be used with smaller modules.
The new device is compatible with an IC control voltage of 4.5 V to 5.5 V and can deliver up to output currents of up to 85mA per channel. Input signal transfer frequency range is 0.5 MHz to 2 MHz, and illumination can be controlled using PWM gradation (0 to 127).
