Texas Instruments · LED Drivers · VQFN-24(4x4)
TLC5928RGER from Texas Instruments, in a VQFN-24(4x4). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | LAT | input | Edge-triggered latch input that transfers the on/off control shift register data to the data latch on its rising edge, and LAT must be toggled only once after the shift data are updated. |
| 2 | OUT0 | output | Constant-current sink output; absolute maximum output voltage is +18 V and absolute maximum dc output current is 40 mA, and outputs may be tied together to increase current. |
| 3 | OUT1 | output | Constant-current sink output; absolute maximum output voltage is +18 V and absolute maximum dc output current is 40 mA. |
| 4 | OUT2 | output | Constant-current sink output; absolute maximum output voltage is +18 V and absolute maximum dc output current is 40 mA. |
| 5 | OUT3 | output | Constant-current sink output; absolute maximum output voltage is +18 V and absolute maximum dc output current is 40 mA. |
| 6 | OUT4 | output | Constant-current sink output; absolute maximum output voltage is +18 V and absolute maximum dc output current is 40 mA. |
| 7 | OUT5 | output | Constant-current sink output; absolute maximum output voltage is +18 V and absolute maximum dc output current is 40 mA. |
| 8 | OUT6 | output | Constant-current sink output; absolute maximum output voltage is +18 V and absolute maximum dc output current is 40 mA. |
| 9 | OUT7 | output | Constant-current sink output; absolute maximum output voltage is +18 V and absolute maximum dc output current is 40 mA. |
| 10 | OUT8 | output | Constant-current sink output; absolute maximum output voltage is +18 V and absolute maximum dc output current is 40 mA. |
| 11 | OUT9 | output | Constant-current sink output; absolute maximum output voltage is +18 V and absolute maximum dc output current is 40 mA. |
| 12 | OUT10 | output | Constant-current sink output; absolute maximum output voltage is +18 V and absolute maximum dc output current is 40 mA. |
| 13 | OUT11 | output | Constant-current sink output; absolute maximum output voltage is +18 V and absolute maximum dc output current is 40 mA. |
| 14 | OUT12 | output | Constant-current sink output; absolute maximum output voltage is +18 V and absolute maximum dc output current is 40 mA. |
| 15 | OUT13 | output | Constant-current sink output; absolute maximum output voltage is +18 V and absolute maximum dc output current is 40 mA. |
| 16 | OUT14 | output | Constant-current sink output; absolute maximum output voltage is +18 V and absolute maximum dc output current is 40 mA. |
| 17 | OUT15 | output | Constant-current sink output; absolute maximum output voltage is +18 V and absolute maximum dc output current is 40 mA. |
| 18 | BLANK | input | Blanks all constant-current outputs when high (outputs forced off) and enables the on/off data latch control when low; LOD and PTW data are latched on its rising edge. |
| 19 | SOUT | output | Serial data output connected to the MSB of the on/off data shift register, with data changing on the rising edge of SCLK; output voltage is limited to -0.3 V to VCC + 0.3 V. |
| 20 | IREF | bidirectional | Constant-current setting pin with an external resistor connected between IREF and GND that sets the sink current of OUT0 through OUT15. |
| 21 | VCC | power_in | Power-supply voltage, specified from 3.0 V to 5.5 V. |
| 22 | GND | power_in | Power ground; all GND lines should be made as wide and short as possible to limit parasitic inductance and resistance. |
| 23 | SIN | input | Serial data input for on/off control; when SIN is high, a '1' is written into the LSB of the on/off control shift register on the rising edge of SCLK. |
| 24 | SCLK | input | Serial data shift clock with Schmitt buffer input that shifts the on/off control shift register by one bit per rising edge, and a rising edge is allowed only 100 ns after a rising edge of LAT. |
| 25 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
