HX-8218 PDF – TFT LCD Source Driver ( Datasheet ) – Himax

Part Number: HX-8218, HX8218A

Function: 960-channel, TFT LCD Source Driver

Manufacturer: HiMAX Technologies

Images:HX-8218 datasheet

Description

HX-8218 is a 960-channel output Source Driver with built-in TCON and DAC. The interface follows digital 8-bits serial/24-bits parallel RGB, or CCIR601/656 input signals and digital control timing signals. The DAC supports transferring digital RGB data to analog RGB data for the internal Source Driver. The TCON generates the 960×240 resolution timing to Source driver and Gate Driver.

The Source Driver implements 2 lines of sample and hold circuits. While sampling video signals, the previously sampled data can be output synchronously through driver output channels. And simultaneous or sequential sampling can be chosen for matching the pixel array type. […]

BP1808 pinout datasheet

 

Description

The BP1808 is a DC/DC constant current LED driver with an integrated 70V/300mΩ MOSFET designed for a wide input-voltage range of 3V to 60V. The BP1808 can be configured as Buck, Boost and Buck-Boost topology.  With a current sense reference of 200mV, the LED current is programmed by an external current sense resistor and the power loss is minimized.

BP1808 offers rich protection functions including VDD under voltage protection, output over voltage protection, cycle-by-cycle peak current limit and thermal regulation.
