# LED6000PHTR

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

LED6000PHTR from STMicroelectronics, in a HTSSOP-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 input that can be used to supply a part of the analog circuitry to increase efficiency at light-load; connect to GND if not used or bypass with 1 µF ceramic capacitor if supplied by auxiliary rail. |
| 2 | VIN | power_in | DC input voltage. |
| 3 | VIN | power_in | DC input voltage. |
| 4 | VCC | power_in | Filtered DC input voltage to the internal circuitry; bypass to signal GND by 1 µF ceramic capacitor. |
| 5 | EN | input | Active high enable pin; connect to VCC pin if not used. |
| 6 | SS | passive | An internal current generator (5 µA typ.) charges the external capacitor to implement soft-start. |
| 7 | SYNCH | bidirectional | Master/slave synchronization for preventing beating noise in low-noise applications or reducing input current RMS value. |
| 8 | COMP | output | Output of error amplifier; compensation network is connected at this pin. |
| 9 | FB | input | Inverting input of error amplifier. |
| 10 | FSW | input | A pull-down resistor to GND selects the switching frequency. |
| 11 | ILIM | input | A pull-down resistor to GND selects the peak current limitation. |
| 12 | DIM | input | A PWM signal in this input pin implements LED PWM current dimming; pulled-down by internal 2 µA current. |
| 13 | LX | passive | Switching node. |
| 14 | LX | passive | Switching node. |
| 15 | BOOT | passive | Connect external capacitor (100 nF typ.) between BOOT and LX pins; gate charge required to drive internal n-DMOS is recovered by internal regulator during off-time. |
| 16 | GND | power_in | Signal GND. |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
