Instructions for Use

1. Power Supply Connections:

   • Connect the Vcc pin to the positive supply voltage (10V to 20V).
   • Connect the COM pin to the ground (GND).

2. High-Side Driver:

   • Connect the HO pin to the gate of the high-side MOSFET.
   • Connect the Vboot pin to the bootstrap capacitor, which is also connected between the source of the high-side MOSFET and the drain of the low-side MOSFET.

3. Low-Side Driver:

   • Connect the LO pin to the gate of the low-side MOSFET.

4. Oscillator Configuration:

   • Connect an external resistor (RT) and capacitor (CT) between the RT/CT pin and ground to set the oscillator frequency.
   • The frequency can be calculated using the formula: ( f = frac{1}{1.1 times R_T times C_T} ).

5. Feedback Input:

   • Connect the FB pin to the feedback network to control the output voltage or current.

6. Ground Connection:

   • Ensure that the GND pin is connected to the system ground.

7. Undervoltage Lockout (UVLO):

   • The device will not operate if the Vcc voltage drops below the UVLO threshold (8.5V typical).

8. Thermal Management:

   • Ensure proper heat dissipation by mounting the device on a heatsink if necessary, especially in high-power applications.

9. Layout Considerations:

   • Keep the layout compact to minimize parasitic inductance and capacitance.
   • Use short and wide traces for power and ground connections to reduce resistance and inductance.

10. Storage and Handling:

    • Store the device in a dry environment to prevent moisture damage.
    • Handle with care to avoid static discharge, which can damage the device.
