Instructions for Use:
- Power Supply Connection: Connect the power supply between VCC and GND pins. Ensure the voltage is within the operating range of 8V to 40V.
- Frequency Setting: Adjust the frequency using external resistors and capacitors connected to the RT/CT pin.
- Duty Cycle Adjustment: Modify the duty cycle by adjusting the voltage on the PWM input pin.
- Output Configuration: The output can be configured for push-pull or open-collector operation depending on the application.
- Thermal Management: Ensure adequate heat dissipation if operating at high currents or in high ambient temperatures.
- Protection Circuits: Utilize the built-in overcurrent and thermal protection features to safeguard the circuit.
- Layout Considerations: Keep power and ground planes wide and short to minimize noise and improve stability.
For detailed design considerations and specific applications, refer to the manufacturer’s datasheet or application notes.
