LPD1886

Insomnia Lighting LPD1886 IC Datasheet LPD1886 IC Datasheet Summary LPD1886 is single-line three-channel with 4096 levels PWM programmable constant current LED driver chip. It is a three-channel dedicated circuit for LED driving and control, internally integrated the bandgap reference, digital interface, PWM control and constant current driving circuit. It can achieve multicolor emitting system of the outdoor led displays, led guardrail tubes and led strips, via the control of peripheral circuit. Features 1. Output three-channel constant current driving, the constant driving current is 17mA, Voltage output up to 12V. 2. Intergrated constant voltage circuit, workable from 5V to 24V by connecting electric resistance in series. Insomnia Lighting3. Single line transmission mode, the speed of DATA is changeable, the MAX is 16MHz. 4. Regeneration mechanism of interior wave form, the signal driving ability is very strong, can support more than 1700pixels'(25FPS) cascade connection, the distance between any two pixels can be more than 6m. 5. Double oscillating circuits are built in, support FREE-RUN mode, the renovate frequency is more than 400Hz. Distinctive design of timing sequence, convenient for the lower cost controller programmable design. 6. Each channel has independent linear PWM grayscale control circuit, 4096 grayscales effect can be really achieved. 7. Intergrated the holistic locking and saving function, each frame data will be locked and saved automatically 10us later...
