HANSCHIP semiconductor · DC-DC Converters · TO-263-5
LM2576HVS-3.3RG from HANSCHIP semiconductor, in a TO-263-5. 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 | VIN | power_in | Unregulated supply input, with a maximum of 55V for the LM2576HV series (40V for LM2576). |
| 2 | Output | output | Switching output of the internal power transistor, which delivers up to 3A to the load, with the output voltage limited to -1V below ground in steady state. |
| 3 | Ground | power_in | Ground pin of the regulator, and the package tab is also connected to ground. |
| 4 | Feedback | input | Feedback sense input that regulates the fixed 3.3V output of the LM2576HV-3.3. |
| 5 | ON/OFF | input | Active-low TTL-compatible shutdown input, with an input range of -0.3V to +VIN, a logic-high threshold of 1.4V typical and a 50µA typical standby current when off. |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
