LD7515AGL from Leadtrend Tech, in a SOT-26. 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 | VCC | power_in | Supply voltage pin. Operating range 4.8 V to 16 V (absolute max 20 V). UVLO ON at ~13 V, OFF at ~4 V; OVP trips at ~18 V. Requires a 0.1-0.47 uF ceramic bypass placed close to the pin. |
| 2 | GND | power_in | Device ground reference. |
| 3 | FB | input | Auxiliary winding voltage sense and Quasi-Resonant detection input. Provides primary-side feedback for CV regulation, QRD trip level ~300 mV (100 mV hysteresis) and FB under-voltage protection at ~1.0 V. Absolute max -0.3 V to 3.3 V. |
| 4 | CS | input | Current sense pin; connect to the emitter/source sense resistor to monitor the switch current. VCS max clamp ~1 V, minimum ~0.15 V; internal leading-edge blanking of ~650 ns. Absolute max -0.3 V to 3.3 V. |
| 5 | COMP | output | Error amplifier output for loop voltage compensation. Internal 2.0 V reference, gm ~85 uA/V, upper clamp ~3.0 V. Requires an external compensation capacitor (470-4700 pF). Absolute max -0.3 V to 3.3 V. |
| 6 | OUT | output | Base drive output for the external BJT power switch. Delivers up to ~60 mA base current (Ib-max), max on-time ~13 us, switching frequency up to 75 kHz. Absolute max -0.3 V to 3.3 V. |
