Application Scenarios & Design Considerations

TRANSISTOR ARRAY WITH 5 NPN TRANSISTORS

Alternative Part Number

  • UC3842AN --: Industry-standard current-mode PWM controller in a DIP-8 package, functionally similar to the TCA671 and widely available as a replacement in power supply designs.
  • SG3524N --: Classic PWM regulator/controller IC with comparable control functions, commonly used as a substitute for older Siemens PWM control devices.
  • TL494CN --: Versatile fixed-frequency PWM control circuit in DIP-16, often used to replace obsolete European PWM controller ICs such as the TCA671.
  • TDA7052 --: Audio power amplifier IC in a similar low-power class, widely available and often used as a substitute in audio driver circuits.
  • LM386 --: Very common low-voltage audio amplifier IC with similar function and pin-compatible usage in many small audio applications.
  • TDA2822 --: Dual low-power audio amplifier IC suitable for similar audio amplification roles, easy to source and cost effective.
