PT6925-HS-TP from PTC Princeton Tech, 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_out | Internal regulator output that powers the IC, specified at 5 to 5.5V with absolute maximum rating of -0.3 to +6V to GND. |
| 2 | COMP | passive | Loop compensation node, with absolute maximum rating of -0.3 to +6V to GND and a COMP pre-charge threshold of 0.8V. |
| 3 | DIM | input | Analog dimming and enable input with a 0.1 to 2.5V dimming range (full output at or above 2.5V) and absolute maximum rating of -0.3 to +6V to GND; leave floating for non-dimming operation. |
| 4 | CS | input | Output current setting pin where a resistor to IC ground sets the LED current as ILED = 300mV / RCS, with absolute maximum rating of -0.3 to +6V to GND. |
| 5 | DR4 | output | Fourth switch drain for the LED string, rated -0.3 to +450V to GND. |
| 6 | DR3 | output | Third switch drain for the LED string, rated -0.3 to +450V to GND. |
| 7 | DR2 | output | Second switch drain for the LED string, rated -0.3 to +450V to GND. |
| 8 | DR1 | power_in | First switch drain that also serves as the IC power input, rated -0.3 to +450V to GND and supporting input voltages from 20 to 400V. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
