LM25017MRX from Texas Instruments, in a SO-8. 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 | RTN | power_in | Ground reference connection for the integrated circuit. |
| 2 | VIN | power_in | Power supply input with operating range of 7.5 V to 48 V. |
| 3 | UVLO | input | Undervoltage lockout comparator input; external resistor divider from VIN to GND programs detection threshold, internal 20 μA current source provides hysteresis, and external pull-down below 0.66 V initiates shutdown. |
| 4 | RON | input | On-time programming input; external resistor to VIN sets switch on-time inversely proportional to VIN with 100 ns minimum on-time required at maximum input voltage. |
| 5 | FB | input | Feedback input to regulation comparator with 1.225 V internal reference; external resistor divider sets output voltage. |
| 6 | VCC | power_out | Regulated power output at 7.6 V nominal (26 mA current limit, 4.5 V UVLO threshold) supplying gate drivers and control circuits; requires 1.0 μF decoupling capacitor. |
| 7 | BST | power_out | Bootstrap capacitor power supply charged from VCC through internal diode when SW pin is low; requires 0.01 μF ceramic capacitor between BST and SW pins. |
| 8 | SW | output | Power switching node driven by integrated high-side and low-side MOSFETs; connects to output inductor and bootstrap capacitor. |
