PT4115B89E-JSM from JSMSEMI, in a SOT-89-5. 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 | SW | bidirectional | Internal power MOSFET drain and switch node; the SW pin maximum current is 1.5 A and the internal MOS on-resistance is 300 mΩ for VIN = 6 V to 30 V. |
| 2 | VSS | power_in | Chip ground (GND) return for the controller and the reference for the DIM and CS thresholds. |
| 3 | DIM | input | Brightness (dimming) control input that accepts PWM or analog dimming; the output turns off and the part enters standby when DIM is below 0.3 V, the maximum DIM pin voltage is 6 V, the maximum dimming frequency is 20 kHz, and the pin may be left floating if dimming is not used. |
| 4 | CS | input | Current-sense input connected to the external sense resistor RCS; the VIN−VCS threshold is 95-105 mV (100 mV typ.) and the CS pin input current is 10 µA, and the sense resistor sets the LED output current. |
| 5 | VIN | power_in | Power supply input; the datasheet specifies a 5.5 V to 30 V operating range, and a 47 µF to 100 µF filter capacitor rated above the maximum input voltage is required at this pin. |
