Pinout
The LM5007MMX is a switching regulator integrated circuit, specifically a step-down (buck) regulator, designed for efficient power management. It is available in an 8-pin MSOP (Mini Small Outline Package). Here’s a brief overview of its pin functions:
1. SW (Switch Output): This pin is connected to the inductor and is the switch node of the regulator.
2. BST (Bootstrap Capacitor): Connected to a bootstrap capacitor, this pin provides a drive voltage higher than the input voltage to the internal NMOS control switch.
3. VIN (Input Voltage): This is the supply voltage input pin.
4. RCL (Current Limit): A resistor connected to this pin sets the peak current limit of the device.
5. FB (Feedback): This pin receives the output voltage via a resistive divider to regulate the output.
6. RTN (Return): Ground reference for the integrated circuit.
7. UVLO (Under-Voltage Lockout): Sets the under-voltage lockout threshold.
8. SS (Soft-Start): Controls the soft-start time to limit inrush current.
This configuration allows the LM5007MMX to efficiently convert higher DC input voltages to lower DC output voltages.
