Instructions for TL494CDRG4

1. Power Supply Connection:

   • Connect the supply voltage (Vcc) to pin 16 and ground (GND) to pin 8.
   • Ensure the supply voltage is within the specified operating range of 8V to 40V.

2. Oscillator Configuration:

   • Connect a timing capacitor between pins 6 and 7.
   • Connect a timing resistor from pin 6 to Vcc.
   • Adjust these components to set the desired oscillator frequency within the range of 400 Hz to 300 kHz.

3. Dead Time Adjustment:

   • Use pin 4 to adjust the dead time between output pulses by connecting a resistor or leaving it floating for minimum dead time.

4. Duty Cycle Control:

   • Pins 2 and 3 are used for error amplifier inputs; connect appropriate feedback networks to control the duty cycle.
   • The duty cycle can be adjusted from 0% to 97%.

5. Output Configuration:

   • Outputs are available on pins 9 through 14. These can be configured as push-pull or open-collector depending on the application.
   • Ensure proper heat sinking if driving high currents.

6. Thermal Considerations:

   • Operate within the specified temperature range (-40°C to 125°C).
   • Provide adequate ventilation or cooling if operating near the upper limit.

7. Storage and Handling:

   • Store in a dry environment within the temperature range of -65°C to 150°C.
   • Follow ESD handling procedures to prevent damage.

For detailed specifications and advanced applications, refer to the manufacturer's datasheet.
