The TOP210PN is a highly efficient, integrated AC-DC, offline power conversion switch from Power Integrations. It combines a full range of features, including integrated EMI, thermal and overvoltage protection, an internal current limit and power factor correction (PFC) circuitry to meet global energy performance standards.

Application Fields

The TOP210PN has a wide variety of applications, including:

• Industrial power supplies
• Lighting
• Computer peripheral equipment
• Automotive power systems
• Telecommunications

The TOP210PN can also be employed in many DC-DC applications, such as digital cameras and video devices.

Working Principle

The TOP210PN employs a full bridge rectifier and an active PFC boost converter to allow a high power factor, wide input voltage range and low total harmonic distortion. Its integrated EMI filter and overvoltage regulator protect against premature failure or damaging transients resulting from AC line disturbances.

The TOP210PN also features an adjustable current limit circuit that limits both differential and Common Mode current. This provides protection against ground faults, overloads, and short circuits, ensuring maximum safety and reliability.

In order to reduce switching losses, the TOP210PN features an internal switched mode power factor correction (SMPFC) circuit. This also helps to minimize EMI/RFI generation and ensure compliance with global efficiency standards.

The TOP210PN also features built-in thermal protection that automatically shuts down the device if the temperature rises above a certain limit. This safeguards both the TOP210PN and the system in which it is installed.

Overall, the TOP210PN is a highly efficient and reliable AC-DC offline switcher that provides robust protection and power factor correction.
