**STMicroelectronics** · LED Drivers · TSSOP-16-EP

LED6000PHR from STMicroelectronics, in a TSSOP-16-EP. 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 | VBIAS | power_in | Auxiliary DC input voltage for analog circuitry power supply; bypass to signal GND with 1 µF ceramic capacitor when used with auxiliary rail, or connect to GND when not used. |
| 2 | VIN | power_in | DC input voltage supply; 4.5 V to 61 V operating range. |
| 3 | VIN | power_in | DC input voltage supply; 4.5 V to 61 V operating range. |
| 4 | VCC | power_in | Filtered DC input voltage for internal circuitry; bypass to signal GND with 1 µF ceramic capacitor. |
| 5 | EN | input | Active high enable control input; connect to VCC pin when enable function is not used. |
| 6 | SS | output | Soft-start capacitor connection pin; internal 5 µA current generator charges external capacitor to set soft-start timing. |
| 7 | SYNCH | bidirectional | Synchronization input/output pin supporting master-slave clock distribution to up to 5 slave devices. |
| 8 | COMP | output | Error amplifier output for external compensation network connection. |
| 9 | FB | input | Inverting input of the error amplifier with nominal reference voltage 0.240 V to 0.260 V. |
| 10 | FSW | input | Switching frequency selection pin; pull-down resistor to GND selects operating frequency from 250 kHz to 1.5 MHz. |
| 11 | ILIM | input | Peak current limit selection pin; pull-down resistor to GND selects current limitation from 0.68 A to 4.1 A. |
| 12 | DIM | input | PWM dimming control input (0 V to VCC); pulled-down by internal 2 µA current for LED brightness modulation. |
| 13 | LX | output | High-side switching node; output of internal n-DMOS connected to output inductor. |
| 14 | LX | output | High-side switching node; output of internal n-DMOS connected to output inductor. |
| 15 | BOOT | power_in | Bootstrap capacitor connection pin (100 nF typical); gate drive charge for internal n-DMOS is recovered by internal regulator during off-time. |
| 16 | GND | power_in | Signal ground reference for all circuits. |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
