6 / 46 page  TLC5951 SBVS127B – MARCH 2009 – REVISED DECEMBER 2009 www.ti.com SWITCHING CHARACTERISTICS At TA = –40°C to +85°C, VCC = 3 V to 5.5 V, CL = 15 pF, RL = 100 Ω, RIREF = 1.2 kΩ, and VLED = 5.0 V, unless otherwise noted. Typical values are at TA = +25°C and VCC = 3.3 V. PARAMETER TEST CONDITIONS MIN TYP MAX UNIT tR0 GSSOUT, DCSOUT 6 15 ns OUTR0-OUTR7, OUTG0-OUTG7, OUTB0-OUTB7, Rise time tR1 with BCR/G/B = FFh and DCRn/Gn/Bn = 7Fh with DC high adjustment 10 30 ns range tF0 GSSOUT, DCSOUT 6 15 ns OUTR0-OUTR7, OUTG0-OUTG7, OUTB0-OUTB7, Fall time tF1 with BCR/G/B = FFh and DCRn/Gn/Bn = 7Fh with DC high adjustment 10 30 ns range tD0 GSSCK ↑ to GSSOUT, DCSCK↑ to DCSOUT 15 25 ns tD1 GSLAT ↑ to GSSOUT 50 100 ns tD2 XBLNK ↓ to OUTR0/G0/B0, OUTR4/G4/B4 off 20 40 ns GSCKR/G/B ↑ to OUTR0/G0/B0, OUTR4/G4/B4 on, tD3 with BCR/G/B = FFh and DCRn/Gn/Bn = 7Fh with DC high adjustment 5 18 40 ns range GSCKR/G/B ↑ to OUTR1/G1/B1, OUTR5/G5/B5 on, tD4 with BCR/G/B = FFh and DCRn/Gn/Bn = 7Fh with DC high adjustment 20 42 73 ns range GSCKR/G/B ↑ to OUTR2/G2/B2, OUTR6/G6/B6 on, tD5 with BCR/G/B = FFh and DCRn/Gn/Bn = 7Fh with DC high adjustment 35 66 106 ns Propagation delay range GSCKR/G/B ↑ to OUTR3/G3/B3, OUTR7/G7/B7 on, tD6 with BCR/G/B = FFh and DCRn/Gn/Bn = 7Fh with DC high adjustment 50 90 140 ns range tD7 Internal latch pulse generation delay from DCSCK 3 5 7 ms GSLAT ↑ to IOUTRn/Gn/Bn changing by dot correction control tD8 (control data are 0Ch → 72h or 72h → 0Ch with DC high adjustment 30 50 ns range), BCR/G/B = FFh GSLAT ↑ to IOUTRn/Gn/Bn changing by global brightness control tD9 (control data are 19h ≥ E6h or E6h ≥ 19h with DCRn/Gn/Bn = 7Fh with 100 300 ns DC high adjustment range) tOUT_ON – TGSCKR/G/B, GSDATA = 001h, GSCKR/G/B = 33 MHz, tON_ERR Output on-time error(1) with BCR/G/B = FFh and DCRn/Gn/Bn = 7Fh with DC high adjustment –15 5 ns range (1) Output on-time error (tON_ERR) is calculated by the formula tON_ERR (ns) = tOUT_ON – TGSCKR/G/B. tOUT_ON indicates the actual on-time of the constant current driver. TGSCKR is the period of GSCKR, TGSCKG is the period of GSCKG, and TGSCKB is the period of GSCKB. 6 Submit Documentation Feedback Copyright © 2009, Texas Instruments Incorporated Product Folder Link(s): TLC5951 |
