HTC Korea TAEJIN Tech · DC-DC Converters · TO-263-5
LM2576HVR-15 from HTC Korea TAEJIN Tech, 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 | Input supply pin for the regulator; the datasheet gives an operating supply voltage range up to 60 V (absolute maximum 63 V). |
| 2 | VOUT | power_out | Regulated output from the internal output switch that drives the external inductor and freewheeling diode; the datasheet specifies 3A guaranteed output current and a fixed 15 V output for this version (LM2576HV-15: 14.25 V to 15.83 V over load and line). |
| 3 | GND | power_in | Ground reference pin for the regulator; the datasheet says to use single-point grounding or a ground plane for best results. |
| 4 | FB/ADJ | input | Output voltage feedback input for the fixed-voltage versions and output adjust input for the adjustable version; the adjustable version has a feedback bias current of 50 nA typical, 100 nA typical to 500 nA maximum at VO = 5 V. |
| 5 | ON/OFF | input | TTL-compatible shutdown input where pulling it to 0 V enables the regulator and pulling it to 5 V disables it, with standby quiescent current of 50 uA typical and 200 uA maximum at VIN = 60 V; the absolute pin voltage range is -0.3 V to VIN. |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
