TL3845DR from Texas Instruments, in a SOIC-14. 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 | COMP | bidirectional | Error amplifier compensation pin for frequency response adjustment with external RC network. |
| 2 | NC | unconnected | Do not connect; no internal connection. |
| 3 | VFB | input | Error amplifier feedback input, 0 to 5.5V recommended operating range, referenced to GND. |
| 4 | NC | unconnected | Do not connect; no internal connection. |
| 5 | ISENSE | input | Current sense comparator input, 0 to 5.5V recommended operating range for pulse-by-pulse current limiting. |
| 6 | NC | unconnected | Do not connect; no internal connection. |
| 7 | RT/CT | bidirectional | Oscillator RC input for frequency timing, 0 to 5.5V recommended operating range. |
| 8 | POWER GROUND | power_in | Output PWM ground terminal and return path for the high-current totem-pole output stage. |
| 9 | GND | power_in | Device power supply ground terminal and reference for analog and digital signals. |
| 10 | OUTPUT | output | PWM output with high-current totem-pole driver, 0 to 30V operating range, ±1A peak current capability. |
| 11 | VC | power_in | Output PWM positive voltage supply for high-current output stage, maximum 30V, D package only. |
| 12 | VCC | power_in | Device positive voltage supply input for logic circuits, maximum 30V recommended operating voltage. |
| 13 | NC | unconnected | Do not connect; no internal connection. |
| 14 | REF | output | Internally trimmed bandgap reference output voltage (approximately 5V), maximum -20mA sink current. |
