LM2574HVM-5.0
Texas Instruments · DC-DC Converters · SOIC-14-300mil
LM2574HVM-5.0 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 it must be soldered to the PCB for best heat transfer. |
| 2 | NC | unconnected | No internal connection, but it must be soldered to the PCB for best heat transfer. |
| 3 | FB | input | Feedback sense input; connect to the midpoint of the feedback divider to set VOUT for the ADJ version, or connect directly to the output capacitor for a fixed-output version. |
| 4 | SIG_GND | power_in | Signal ground; the ground reference for internal references and logic, to be connected to system ground. |
| 5 | ON/OFF | input | Enable input: high = OFF, low = ON; connect to GND to enable the regulator and do not leave this pin floating. |
| 6 | PWR_GND | power_in | Power ground; connect to system ground and to the ground pins of CIN and COUT, keeping the path to CIN as short as possible. |
| 7 | NC | unconnected | No internal connection, but it must be soldered to the PCB for best heat transfer. |
| 8 | NC | unconnected | No internal connection, but it must be soldered to the PCB for best heat transfer. |
| 9 | NC | unconnected | No internal connection, but it must be soldered to the PCB for best heat transfer. |
| 10 | VIN | power_in | Supply input to the collector of the high-side transistor; connect to the supply and bypass capacitor CIN, with the VIN-to-CIN and PWR_GND path kept as short as possible (supply 60 V max for LM2574HV). |
| 11 | NC | unconnected | No internal connection, but it must be soldered to the PCB for best heat transfer. |
| 12 | OUTPUT | output | Emitter of the power transistor and switching node; connect to the inductor and the cathode of the external diode. |
| 13 | NC | unconnected | No internal connection, but it must be soldered to the PCB for best heat transfer. |
| 14 | NC | unconnected | No internal connection, but it must be soldered to the PCB for best heat transfer. |
