TCWIN’s 16-bit-per-channel LED driver in a 2.2 x 2.2 x 1.05 mm six-pad package (LCSC: SMD2020-6P). Sheet version A1, cover date 2021-11-15, the oldest TCWIN sheet in the set. Pins (p5): 1 DO, 2 NC (the PCB must connect it to pin 5 DIN), 3 GND, 4 FDIN (backup data input), 5 DIN, 6 VDD (+5 V). Numbered counter-clockwise from the polarity-marked bottom-right corner. The suggested land pattern joins pads 2 and 5 with one bar.
The sheet is the only TCWIN text that explains the backup port: “a backup communication port, so that when one chip in the cascade is damaged the following ones are not affected”. It describes a 3-channel high-grey constant-current driver with gamma correction, a 48-bit data frame (G15…G0 R15…R0 B15…B0, high bit first, GRB order), a separate 15-bit gain word (five bits per channel, default 08H = 3.63 mA, table 0.71-12.00 mA), 1.3 MHz data rate and 4 kHz PWM.
Datasheets disagree with themselves: the feature list says the default constant-current output is 3.5 mA while the gain table (p9) says default setting 08H gives 3.63 mA; the absolute-maximum table gives VDD 3.0-5.5 V while the electrical table gives 4 / 5 / 5.5 V; the sheet never says how the 15-bit gain word is sent relative to the 48-bit frame. LCSC lists TX1816ZWBN-F01 as a 5-pin 2.2 x 2.2 mm part while the only TX1816 sheet is six-pin. The cover says 2.2 x 2.2 x 1.05 mm while the LCSC package name is “2020”.

| No datasheet is listed on LCSC for this SKU. Package, pin order and drawing are taken from the sibling sheet TX1816ZLN-F01 because both share IC code 1816 and package letter Z; that is an inference from the part number, not something any sheet states. Drive current, timing window and the meaning of the remaining letters are not confirmed for this SKU. LCSC lists this SKU as a 5-pin 2.2 x 2.2 mm package while the sheet for TX1816ZLN-F01 is six-pin, so the pinout is NOT inherited. Stock 0 when checked. LCSC stock 0 on 2026-10-15. | ||||||||
