PT4115EE89E 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 | Switch output. Drain of the internal N-Channel MOSFET switch; connects to the inductor in the buck topology. Rated -0.3V to 55V, continuous SW current up to 1.5A with typical RDS(on) of 0.4 Ohm. |
| 2 | GND | power_in | Signal and power ground. Must connect directly to the ground plane for proper operation and thermal performance. |
| 3 | DIM | input | Logic level dimming input. Drive DIM low (<=0.3V) to disable the current regulator, high (>=2.5V) to enable full LED current. Accepts PWM (100Hz to 20kHz) or DC (0.5V to 2.5V) for brightness control; internally pulled up ~200k to a 4.2V internal supply. Absolute max -0.3V to 6V. |
| 4 | CSN | input | Current sense input. Connect to the LED-side of the external high-side current-sense resistor (Rcs); the device regulates VIN-VCSN to a typical 200mV (194-206mV) to set the average LED current. Absolute max +0.3V to -6.0V with respect to VIN. |
| 5 | VIN | power_in | Input supply pin. Must be locally bypassed with a ceramic capacitor. Operating range 6V to 50V; absolute max -0.3V to 55V; UVLO typically 4.5V rising with 0.3V hysteresis. |
| EP | Exposed PAD | passive | Exposed thermal pad on the underside of the SOT89-5 package. Internally connected to GND; mount to a ground copper pour for lower thermal resistance (theta_JA = 45 C/W). |
