3 Description

is a 16-channel, constant current sink driver. Each

device integrates 16 constant current sinks with

SRAM for brightness storage. The device connects to

each other by two-wire serial interface in diasy chain

topology and supports up to 1024 devices for 16,000

local dimming zones.

To optimize system effiency, the device equips with

adaptive headroom voltage control scheme to directly

control DC/DC. Only the FB pin from last device in

serial chain should be connected to DC/DC to acheive

simplified system layout. The device also integrates

minimum brightness update latency, black insertion

and VRR features to improve display quality.

TLC696x1 has three error flags: LED open detection

(LOD), LED short detection (LSD) and thermal

shutdown detection (TSD) for diagnostic. The device

implements two options for readback including

UART/INT and SOUT/CLK_O which is programmable

by register.
