LM5002MAX from Texas Instruments, in a SOIC-8. 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 | SW | tri_state | Switch output at drain of internal 75-V MOSFET with tri-state control, switching to high-Z when 0.5-A cycle-by-cycle current limit is triggered. |
| 2 | VIN | power_in | Input supply pin accepting 3.1 V to 75 V from external DC source; input transient filtering is recommended. |
| 3 | VCC | power_in | Regulated 6.9-V bias output tracking VIN or external 7-12-V input to reduce dissipation; minimum 0.47-µF ceramic capacitor required. |
| 4 | GND | power_in | Ground connection providing internal reference for regulator control functions and MOSFET current sensing. |
| 5 | RT | input | Frequency programming input with external resistor to GND setting oscillator range from 50 KHz to 1.5 MHz, accepting 100-pF AC-coupled external synchronization pulses. |
| 6 | FB | input | Feedback input to inverting terminal of error amplifier with 1.26-V internal reference on non-inverting terminal for output regulation. |
| 7 | COMP | output | Error amplifier open-drain output with 5-kΩ pullup resistor, requiring external loop compensation network between COMP and FB pins. |
| 8 | EN | input | Enable/UVLO input with dual-threshold logic: below 0.45 V triggers shutdown (95-µA quiescent), above 1.26 V enables normal operation, with internal 6-µA pullup when unconnected. |
