DESCRIPTION

UTC  UL1030 is designed for driving chip of LED lighting

system design, it uses advanced high voltage CMOS technology,

provide 3 channel constant current drive and gray scale

modulation output, especially in the dissociation with mutual grey

level in the full-color lighting system.

UTC UL1030 includes serial shift register and concatenation

driver circuit, grey level data shift into serial shift register in the

clock, and transfer saving, it  transfer to interface 3 after

pulse-width modulate, then output, serial shift register and

grey-level counter can be controlled by different clock signal. In

the meantime, UTC UL1030 driver data signal and control signal,

and output next circuit.

FEATURES

* 3 channel driver output, maxim current per channel is 45mA, LED light voltage can reach 12V

* Output adopt In-Rush online feedback constant-current driver structure, compatible with constant-voltage

module, it also can contact outside equipment and transfer to higher voltage or current output driver

* Built-in LDO voltage-stabilizing circuit, voltage range : 3~8V, and have 5V stabilizing voltage output

* Adopt self-add token ring technology dual shift line, shift clock can reach 25MHz

* Directly input grey-level data, it is transfer to 256 output with reverse-gamma regulator after inside

SUPER-PWM technology, e. g, adopt built-in oscillator as grey-level clock, it support

FREE-RUN module output, especially can be used in low-cost controller

* Data clock signal is drived strongly to next chip to enhance level after built-in phase-lock circuit

* High-voltage CMOS technology, industrial design, with extra-good interference immunity
