FAQs
What is TOP250R?
The TOP250R is a monolithic high-voltage switcher IC (integrated circuit) designed by Power Integrations. It is commonly used in offline power conversion applications, such as AC-DC power supplies, LED drivers, and industrial power systems.
How Does TOP250R Work?
The TOP250R functions as a high-voltage switcher by converting AC input voltage to a regulated DC output voltage. It utilizes a pulse frequency modulation (PFM) control scheme to regulate the output voltage efficiently. The IC incorporates protection features such as overcurrent protection and thermal shutdown for reliable operation.
How Many Pins does TOP250R have and What are the Functions of the Pinout Configuration?
The TOP250R is housed in a 7-pin TO-220 package. The pinout configuration includes:
- Vin: Input voltage pin.
- Vout: Output voltage pin.
- FB: Feedback pin for output voltage regulation.
- GND: Ground pin.
- EN/UV/OVP: Enable, undervoltage lockout, and overvoltage protection pin.
- BP/MODE: Burst mode control pin.
- Src/RTN: Primary bias winding source and return pin.
What are the Pros and Cons of TOP250R?
Pros:
- High Voltage Capability: Suitable for offline power applications with high input voltages.
- Efficiency: Utilizes PFM control for efficient power conversion.
- Protection Features: Includes overcurrent protection and thermal shutdown for system reliability.
- Compact Package: Housed in a TO-220 package for easy mounting and heat dissipation.
- Versatility: Suitable for various power supply and LED driver designs.
Cons:
