Always verify details of parts you are evaluating, as these parts are offered as suggestions for what you are looking for and are not guaranteed.
TL494IDR Frequently Asked Questions (FAQ)
-
The maximum voltage rating for the TL494IDR is 40V. However, it's recommended to operate within 30V to ensure reliable operation.
-
The inductor value depends on the output voltage, current, and switching frequency. A good starting point is to use the inductor selection guide in the datasheet or online tools like TI's Power Stage Designer.
-
The soft-start pin (SS) is used to slowly ramp up the output voltage during startup to prevent inrush currents. Connect a capacitor from SS to GND and adjust the value to set the soft-start time.
-
Connect the external clock signal to the RT/CT pin and set the RT/CT pin high to enable synchronization. Ensure the clock frequency is within the recommended range (100 kHz to 500 kHz).
-
The maximum duty cycle for the TL494IDR is 95%. However, it's recommended to operate within 80% to 90% duty cycle for reliable operation and to prevent over-voltage conditions.
