XR75100ELTR-F from MaxLinear, in a QFN-16-EP(3x3). 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 | GL | output | Driver output for the low-side N-channel synchronous MOSFET. |
| 2 | NC | unconnected | Internally not connected; leave this pin floating. |
| 3 | SW | passive | Lower supply rail for the high-side gate driver GH; connect to the junction between the two external N-channel MOSFETs. |
| 4 | GH | output | Driver output for the high-side N-channel switching MOSFET. |
| 5 | BST | power_in | High-side driver supply; connect a 0.1µF bootstrap capacitor between BST and SW. |
| 6 | ILIM | passive | Over-current protection programming; connect with a resistor to the drain of the low-side MOSFET. |
| 7 | EN/MODE | input | Tri-level precision enable/mode pin: below 1.8V shuts the controller down, 2.0V to 2.9V selects Forced CCM, and above 3.1V selects DCM/CCM depending on load. |
| 8 | TON | passive | Constant on-time programming pin; connect a resistor (RON) to AGND. |
| 9 | SS | passive | Soft-start pin; connect an external capacitor between SS and AGND to set the soft-start rate from the 10µA internal source. |
| 10 | PGOOD | output | Open-drain power-good output that is pulled low when VOUT is outside regulation. |
| 11 | FB | input | Feedback input to the feedback comparator; connect a resistor divider to VOUT and GND to program VOUT against the 0.6 V reference. |
| 12 | AGND | power_in | Analog ground; the control circuitry of the IC is referenced to this pin. |
| 13 | AGND | power_in | Analog ground; the control circuitry of the IC is referenced to this pin. |
| 14 | VIN | power_in | IC supply input that provides power to the internal LDO; input range is 5.5V to 40V. |
| 15 | VCC | power_out | Output of the internal LDO (about 5.0V); for operation from a 5V rail, VCC should be shorted to VIN. |
| 16 | PGND | power_in | Low-side driver ground. |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
