SBVS237 – MARCH 2014 TLC5955 48-Channel, 16-Bit, PWM LED Driver with DC, BC, LED Open-Short Detection,
and Internal Current Setting
1 Features 3 Description The TLC5955 is a 48-channel, constant-current sink
driver. Each channel has an individually-adjustable,
pulse width modulation (PWM), grayscale (GS)
brightness control with 65,536 steps and 128 steps of
constant-current dot correction (DC). DC adjusts
brightness deviation between channels. All channels
have a 128-step global brightness control (BC). BC
adjusts brightness deviation between the R, G, B
color group. The eight-step maximum current control
(MC) selects the maximum output current range for
all channels of each color group. GS, DC, BC, and
MC data are accessible with a serial interface port. 1 48 Constant-Current Sink Output Channels
Sink Current Capability with Maximum MC, DC,
and BC Data:
– 23.9 mA (VCC ≤ 3.6 V, MC = 5) …
