FAQs

What is TOP244P?

The TOP244P is a highly integrated offline switcher IC (integrated circuit) designed by Power Integrations. It combines a power MOSFET, PWM control, fault protection, and other features into a single package, making it ideal for use in power supply applications.

How Does TOP244P Work?

The TOP244P operates as an offline switcher IC that transforms AC input voltage into regulated DC output voltage. It uses a pulse-width modulation (PWM) control to regulate the output voltage efficiently. The IC integrates various protection features such as overvoltage protection and overcurrent protection to ensure safe operation.

How Many Pins does TOP244P have and What are the Functions of the Pinout Configuration?

The TOP244P is enclosed in a 7-lead through-hole package. The pinout configuration includes:

  • AC: Input pin for the AC voltage.
  • DC: Output pin for the regulated DC voltage.
  • RT: External resistor connection for setting switching frequency.
  • BP: External capacitor connection for frequency jittering.
  • GND: Ground pin.
  • ON/OFF: On/Off control pin.
  • Drain: Power MOSFET drain connection.

What are the Pros and Cons of TOP244P?

Pros:

  • High Integration: Combines multiple functions into a single IC, reducing component count.
  • Efficient Regulation: Uses PWM control for efficient voltage regulation.
  • Protection Features: Includes built-in protection mechanisms for reliable operation.
  • Compact Design: Suitable for compact power supply designs.

Cons:

  • Feedback Circuitry: Requires careful design of feedback and compensation circuits for stability.
  • Heat Dissipation: May need additional heat sinking for high-power applications.

Are There Any Equivalents/Alternatives to TOP244P for Recommendation?

  • The TOP245P from Power Integrations is a similar offline switcher IC with slightly different specifications.
  • Alternatives to the TOP244P include the NCP4305 from ON Semiconductor and the LNK304 from Power Integrations.
