HANSCHIP semiconductor · DC-DC Converters · TO-263-5
LM2575HVS-ADJRG 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; maximum supply voltage is 55 V for the LM2575HV (40 V for LM2575), and ON/OFF may range from -0.3 V to +VIN. |
| 2 | Output | output | Switch output of the internal power transistor, rated for 2 A load current with 5.8 A typical current limit, and output voltage to ground of -1 V (steady state) maximum. |
| 3 | Ground | power_in | Ground pin; the package tab is also connected to ground. |
| 4 | Feedback | input | Feedback input that senses the output voltage via a divider; adjustable version regulates this pin to VREF of 1.23 V (VOUT = VREF x (1 + R2/R1)). |
| 5 | ON/OFF | input | Active-low shutdown input (TTL compatible); logic high (above 2.2 V to 2.4 V max threshold) shuts the regulator off to about 50 uA standby current, low (below 1.2 V typical) enables it, and voltage range is -0.3 V to VIN. |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
