TP8005 from TPOWER, in a SOT-89-5L. 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 | Internal power MOSFET drain. Switching node connecting to the inductor and Schottky freewheel diode; rated -0.3V to +40V relative to GND with 0.35Ω typical Rds(on) and 1.2A continuous current capability. |
| 2 | GND | power_in | Chip ground reference. Also tied internally to the exposed thermal pad. |
| 3 | DIM | input | Chip enable, analog dimming, and PWM dimming input. Internal 200KΩ pull-up to a 5V regulator; VDIM<0.3V shuts the chip down, VDIM>2.5V gives full LED current, analog dimming range 0.5V-2.5V, PWM up to 50kHz. Abs-max -0.3V to +6V. |
| 4 | CS | input | High-side output current sense input. Sense resistor RCS is connected between VIN and CS; average sense voltage VIN-VCS is typically 98mV (A grade) or 102mV (B/C grade) with ±15% hysteretic ripple. Abs-max ±1.0V relative to VIN. |
| 5 | VIN | power_in | Power supply input, 5V-36V operating (abs-max 40V). Bypass capacitor must be placed close to this pin to GND. UVLO rising ~4.2V, falling ~4.0V; typical operating current 150µA. |
| EP | Exposed PAD | power_in | Thermal exposed pad on the bottom of the SOT89-5L package, electrically connected to chip ground. Solder to a GND copper pour to improve heat dissipation. Not present on the SOT23-5L variant. |
