PT4115B89E-B from PowTech CR PowTech Shanghai, in a SOT-89-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | SW | output | Drain of internal N-Ch MOSFET switch; delivers switched output current to inductor and LED circuit. |
| 2 | GND | power_in | Signal and power ground; connect directly to ground plane for low thermal resistance. |
| 3 | DIM | input | Logic level dimming input; accepts DC voltage (0.5V-2.5V) or PWM signal up to 50kHz for brightness control with 5000:1 range. |
| 4 | CSN | input | Current sense input; measures voltage across external sense resistor (VIN−VCSN = 95-105mV for B type) to regulate output current within ±5% accuracy. |
| 5 | VIN | power_in | Input supply pin; accepts 6V-30V and must be locally bypassed with low ESR capacitor. |
