DX1033E from Dersem, in a ESOP-8. 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 | VDD | power_in | Chip supply input, clamped to about 5.2 V typical with an absolute maximum of -0.3 to 6.0 V, and must be decoupled with at least 1.0 uF placed close to the pin. |
| 2 | PWM1 | input | PWM dimming input for output channel 1 where high enables the output and low turns it off, with an internal 100 uA pull-up, an absolute maximum of -0.3 to 6.0 V, and a minimum response time of 50 ns. |
| 3 | PWM2 | input | PWM dimming input for output channel 2 where high enables the output and low turns it off, with an internal 100 uA pull-up, an absolute maximum of -0.3 to 6.0 V, and a minimum response time of 50 ns. |
| 4 | PWM3 | input | PWM dimming input for output channel 3 where high enables the output and low turns it off, with an internal 100 uA pull-up, an absolute maximum of -0.3 to 6.0 V, and a minimum response time of 50 ns. |
| 5 | CS | passive | Current-setting pin where an external resistor sets the output current of all three channels, with a regulation voltage of about 1.2 V typical and an absolute maximum of -0.3 to 6 V. |
| 6 | IOUT3 | output | Constant-current driver output for channel 3, rated for 20 to 350 mA and withstanding up to 50 V. |
| 7 | IOUT2 | output | Constant-current driver output for channel 2, rated for 20 to 350 mA and withstanding up to 50 V. |
| 8 | IOUT1 | output | Constant-current driver output for channel 1, rated for 20 to 350 mA and withstanding up to 50 V. |
| 9 | GND | power_in | Chip ground, which is the package base (exposed pad) and should be connected to a copper area on the PCB for heat dissipation. |
