Instructions for Using KA3525A (SG3525A) DIP-16

  1. Supply Voltage (Vcc):

    • Connect the supply voltage to pin 16 (Vcc). Ensure the voltage is within the specified range (8V to 35V).
    • Ground the circuit by connecting pin 8 to ground.

  2. Output Frequency (fsw):

    • Set the switching frequency using external resistors and capacitors connected to pins 5 (RT) and 6 (CT).
    • The formula for calculating the frequency is ( f_ = frac{1.1}{R_T times C_T} ).

  3. Dead Time (td):

    • The dead time is set internally and typically ranges from 0.5 to 2.5 μs. No external components are required for this setting.

  4. Output Current:

    • The maximum output current for both sourcing and sinking is 600 mA. Ensure that the load does not exceed this limit to avoid damage.

  5. Duty Cycle:

    • Adjust the duty cycle using the error amplifier and feedback network. Connect the feedback signal to pin 1 (FB).

  6. Reference Voltage (Vref):

    • The internal reference voltage is 5.0 V. It can be used as a stable reference for the error amplifier.

  7. Error Amplifier:

    • Connect the error amplifier inputs to pins 2 (IN+) and 3 (IN-). The output of the error amplifier is connected to the PWM comparator.

  8. Soft-Start:

    • Implement soft-start by connecting a capacitor to pin 4 (SS). The typical soft-start time is 1 ms, but it can be adjusted by changing the capacitor value.

  9. Shutdown:

    • To put the IC into shutdown mode, pull pin 10 (SHDN) low. The quiescent current in shutdown mode is approximately 0.5 mA.

  10. Power Dissipation:

    • Ensure proper heat dissipation if operating at high temperatures or with high power dissipation. Derate the power dissipation above 70°C.

  11. Layout Considerations:

    • Use short, wide traces for power and ground connections to minimize inductance.
    • Place bypass capacitors close to the Vcc and ground pins to filter out noise.

By following these instructions and parameters, you can effectively use the KA3525A (SG3525A) in your power supply or control circuit designs.
