PT4115ME89E from PowTech CR PowTech Shanghai, 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 | output | Drain of the internal power switch; absolute maximum rating is -0.3 to 40 V and the switch output current is rated 1.2 A max. |
| 2 | GND | power_in | Signal and power ground for the device. |
| 3 | DIM | input | Switch enable and analog/PWM dimming input; absolute maximum is -0.3 to 6 V, PWM high level is 2.5 V min, PWM low level is 0.2 V max, and the analog dimming range is 0.5 V to 2.5 V. |
| 4 | CSN | input | Current sense input; the sense resistor is connected between CSN and VIN, and the average sense voltage is 100 mV typical (97 to 103 mV) with absolute limits of +0.3 to -6.0 V relative to VIN. |
| 5 | VIN | power_in | Power supply input, rated 6 V to 36 V with an absolute maximum of -0.3 to 40 V; a bypass capacitor must be placed close to this pin. |
