LM25180NGUR Typical application Circuitry

LM25180NGUR

The LM25180NGUR from Texas Instruments is a monolithic controller designed for the isolated Fly-Buck topology. This versatile device can operate from input voltages between 4.5 V to 65 V. Let's look at how to connect this integrated circuit to your circuit design:

1. Input Power Source: Pin VIN (Pin 3) is where you will connect your DC power source, which can range from 4.5V to 65V. Make sure to decouple this pin with a ceramic capacitor of 1µF to AND (Pin 4) close to the device.

2. Feedback Resistor Network: CFB (Pin 1) pin is used for the feedback from the output. Put a resistor divider connected to the output and this pin to change the output voltage. This pin's internal reference voltage is 2.5 V.

3. Compensation Network: COMP (Pin 2) pin is used to compensate the feedback loop. Typically, a series resistor and capacitor network from this pin to AND (Pin 4) is used.

4. Ground Pins: AND (Pin 4) and PGND (Pin 5) are the analog and power ground pins, respectively. They ought to be joined to your circuit's ground plane.

5. Output to Switching Transistor: GATE (Pin 8) is the output from the controller to the gate of the external switching MOS FET. The appropriate MOS FET's gate should be linked to this pin.

6. Bootstrap Circuit: BST (Pin 7) pin is used to provide the drive voltage to the high-side switch. This pin and the SW (Pin 6) should be connected via a bootstrap capacitor.The SW (Pin 6) pin is the switching node that connects to the source of the high-side switch.

7. Enable and Under-voltage Lockout (UV LO): The EN/UV LO (Pin 10) pin is used to enable the device and set the UV LO threshold. Connect a resistor divider from VIN (Pin 3) to this pin to set the UV LO threshold.

8. Synchronization and Frequency Set: The RT/SYNC (Pin 9) pin is used to set the switching frequency of the device and to synchronize the device to an external clock. Connect a resistor from this pin to AND (Pin 4) to set the frequency.

9. Power Good (PG): The GOOD (Pin 11) is an open-drain output that indicates when the FB voltage is within the regulation limits.

Always remember to follow the guidelines provided in the data sheet of the LM25180NGUR for optimal performance and safety. Proper component selection, layout, and thermal management are crucial for successful operation.
