LPD-8803/8806 Datasheet
LPD8803/LPD8806 as a new generation of driver chips are designed for the LED lighting
system, which uses industrial grade CMOS process, providing multi-channel constant
current driver and grayscale modulation output, it is programable, LPD8803 and LPD8806
output 3chanhel and 6 channel respectively,signal particularly suitable for discrete multi-
gray full-color lighting system.
Features
1. Constant current driving mode, the default driving current is 18mA, supporting
LED lighting voltage up to 12V.
2. LPD8803 support three-way output (pin downward compatible with LPD6803), LPD8806
support the six outputs (pin arrangement conducive to single-panel layout).
3. Two-wire control mode, the shift clock up to 20MHz.
4. Unique data clock regeneration mechanism, super signal drive capability, support
cascading length over 2000 pixels.
5. Built-in 1.2M oscillation circuit, support FREE-RUN mode, easy to programable design
(refresh rate greater than 4000Hz).
6. Built-in 256 independent PWM grayscale control circuit for each channel, 1024
grayscale effect can be achieved by programming.
7. The seven output polarity is Optional ,support an external drive or as a source of
high-power LED driver circuit.
8. Industrial-grade design, input signal processing Schmidt,
strong anti-interference performance.
Applications
1. LED decorative lighting system
2. PWM signal generator
3. LCD backlight driver

Timing Parameters
Inner constant current drive mode:
The mode (OMODE = high level or left floating) is applied when the VDD voltage is not
greater than 12V and the current of each channal is less than 18mA, if VDD <5.5V, the
figure above within the blue dashed box can be omitted, just connect VDD to VCC directly .
When the figure above within the blue dashed box is omitted, the constant current ILED =
18mA (pls Note that after connected, in order to maintain the constant current state, the
conduction-to-ground output voltage VOUT must be between 0.8-5V range). The RL here is
the resistor for current limited, it can be deleted if you don't need it, when RL is more than
several10ohms, the ILED is adjustable. Also the RL is helpful to contribute the power
dissipation PD of the chip, and to improve the working stability.
When designing the circuits, pls note that the power dissipation PD should not bigger than
the maximum PDMAX, the PD = = ΣILEDX * VOUTX + PIC(PIC is the basic power comsuption of
the IC, normally no more than 25mW ) .
