LM2574HVMX-15
Texas Instruments · DC-DC Converters · SOIC-14-300mil
LM2574HVMX-15 from Texas Instruments, in a SOIC-14-300mil. 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, but must be soldered to PCB for best heat transfer. |
| 2 | NC | unconnected | No internal connection, but must be soldered to PCB for best heat transfer. |
| 3 | FB | input | Feedback sense input pin. Connect to the midpoint of feedback divider to set VOUT for ADJ version or connect this pin directly to the output capacitor for a fixed output version. |
| 4 | SIG_GND | power_in | Signal ground pin. Ground reference for internal references and logic. Connect to system ground. |
| 5 | ON/OFF | input | Enable input to the voltage regulator. High = OFF and low = ON. Connect to GND to enable the voltage regulator. Do not leave this pin float. |
| 6 | PWR_GND | power_in | Power ground pins. Connect to system ground and SIF GND, ground pins of CIN and COUT. Path to CIN must be as short as possible. |
| 7 | NC | unconnected | No internal connection, but must be soldered to PCB for best heat transfer. |
| 8 | NC | unconnected | No internal connection, but must be soldered to PCB for best heat transfer. |
| 9 | NC | unconnected | No internal connection, but must be soldered to PCB for best heat transfer. |
| 10 | VIN | power_in | Supply input pin to collector pin of high-side transistor. Connect to power supply and input bypass capacitors CIN. Path from VIN pin to high frequency bypass CIN and PWR GND must be as short as possible. |
| 11 | NC | unconnected | No internal connection, but must be soldered to PCB for best heat transfer. |
| 12 | OUTPUT | output | Emitter pin of the power transistor. This is a switching node. Attached this pin to an inductor and the cathode of the external diode. |
| 13 | NC | unconnected | No internal connection, but must be soldered to PCB for best heat transfer. |
| 14 | NC | unconnected | No internal connection, but must be soldered to PCB for best heat transfer. |
