# IRS2505LTRPBF

**Infineon Technologies** · Gate Drive ICs · SOT-23-5

IRS2505LTRPBF from Infineon Technologies, in a SOT-23-5. 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 | CMP | output | PFC error amplifier compensation pin, with an external compensation capacitor CCMP of 0.68 µF recommended and an internal clamp of 10.2V nominal to COM. |
| 2 | COM | power_in | IC power and signal ground, to which all voltage parameters in the absolute maximum ratings are referenced. |
| 3 | VCC | power_in | Logic and gate drive supply voltage, clamped internally at 20.8V nominal with a 25 mA absolute maximum supply current and a 0.1 µF filter capacitor recommended. |
| 4 | PFC | bidirectional | PFC gate driver output and zero-crossing detection pin, pulling the MOSFET gate to about VCC-1V during on-time and clamping to about one diode forward drop during off-time. |
| 5 | VBUS | power_in | DC bus sensing input for over-voltage protection (VBUSOV+ 4.50V typical) and over-current protection (VBUSOC+ 0.53V typical), with an absolute voltage range of -0.3V to VCC+0.3V. |
