XH2576-5.0 from XINLUDA, in a TO-263-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VIN | power_in | Unregulated DC input supply. Operating range 7 V to 40 V (60 V for HV version); absolute maximum 45 V. Requires a local bypass capacitor (typ. 100 uF aluminum electrolytic) close to the pin for stable operation. |
| 2 | OUTPUT | output | Internal 3 A NPN power switch emitter output. Connects to the external inductor and to the catch (Schottky) diode cathode; this is the switching node of the buck converter. |
| 3 | GND | power_in | Device ground and thermal reference. On the TO-263 (DDPAK) package this pin is tied to the exposed tab; PCB copper area around this pad sets thermal resistance (theta_JA = 32-73 C/W depending on copper). |
| 4 | FEEDBACK | input | Regulation feedback input to the internal error amplifier. On the fixed 5.0 V version this pin is internally divided (R2 = 3.1 k, R1 = 1.0 k) and is connected directly to the regulated output node. On the ADJ version an external divider sets VOUT (Vref = 1.230 V). |
| 5 | ON/OFF | input | TTL-compatible active-low shutdown control (bar over ON/OFF). Logic LOW (or tied to GND) enables the regulator; logic HIGH forces low-power standby (~50 uA typ). Input voltage range: -0.3 V to +VIN. Do not float. |
