Texas Instruments · Charge Pumps · SOIC-16-300mil
LT1054CDWR from Texas Instruments, in a SOIC-16-300mil. 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 | NC | unconnected | No internal connection. |
| 2 | NC | unconnected | No internal connection. |
| 3 | FB/SD | input | Shutdown input for low IQ operation or feedback input for error amplifier regulation; pull below threshold (≈0.45V) for shutdown; rated 0V to VCC. |
| 4 | CAP+ | input | Positive plate of the external charge-transfer capacitor (CIN). |
| 5 | GND | power_in | Ground reference terminal for the device. |
| 6 | CAP- | input | Negative plate of the external charge-transfer capacitor (CIN). |
| 7 | NC | unconnected | No internal connection. |
| 8 | NC | unconnected | No internal connection. |
| 9 | NC | unconnected | No internal connection. |
| 10 | NC | unconnected | No internal connection. |
| 11 | VOUT | output | Regulated output voltage; unregulated value approximately −VCC reduced by voltage loss, typically 1.1V at 100mA output current. |
| 12 | VREF | power_in | Internal reference voltage of 2.5V nominal; supplies the feedback divider network with maximum output current of approximately 60µA. |
| 13 | OSC | input | Oscillator control pin for adjusting or synchronizing the switching frequency; internal nominal frequency is 25kHz, rated 0V to VREF. |
| 14 | VCC | power_in | Device supply voltage input; operating range 3.5V to 15V. |
| 15 | NC | unconnected | No internal connection. |
| 16 | NC | unconnected | No internal connection. |
