LM5001IDQ1 from Texas Instruments, in a SOIC-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 | SW | output | Switch pin, the drain terminal of the internal 75-V N-channel power MOSFET (440 mΩ on-resistance), so layout should keep the SW connections short and wide. |
| 2 | VIN | power_in | Input supply pin with a nominal operating range of 3.1 V to 75 V; VCC tracks VIN up to 6.9 V and the absolute maximum VIN to GND is 76 V. |
| 3 | VCC | power_in | Bias regulator output (regulated to 6.9 V) or input for an external 7 V to 12 V bias supply, requiring a 0.47-µF or greater ceramic decoupling capacitor, and never to exceed 14 V or the VIN voltage. |
| 4 | GND | power_in | Ground pin, the internal reference for the regulator control functions and the power MOSFET current sense resistor connection. |
| 5 | RT | input | Oscillator frequency programming pin; a resistor to GND sets the switching frequency from 50 kHz to 1.5 MHz, and it accepts synchronization pulses through a recommended 100-pF coupling capacitor. |
| 6 | FB | input | Feedback input from the regulated output voltage to the inverting input of the error amplifier, whose internal non-inverting reference is 1.26 V; the absolute maximum rating for FB to GND is 7 V. |
| 7 | COMP | output | Open-drain output of the internal error amplifier with an internal ~5-kΩ pull-up, used for loop compensation between COMP and FB and optionally for an opto-coupler bias or soft-start; the absolute maximum rating for COMP to GND is 7 V. |
| 8 | EN | input | Shutdown and undervoltage-lockout input; below 0.45 V the controller shuts down, between 0.45 V and 1.26 V it is in standby, and above 1.26 V it is fully enabled, with a 6-µA internal pull-up when left unconnected and a 14 V absolute maximum. |
