詳細說明

STATE OF THE ART PRIMARY SIDE SWITCH FOR AC/DC CONVERTERSThe new VIPer53E includes a PWM driver, an MDmesh MOSFET, a start-up high voltage current source and several on-chip protection circuits. The VIPer53E is an alternative choice to the VIPer53 when only the secondary regulation is required in a power supply. Like the standard VIPer53, the new version is housed in surface mounting DIP-8 and PowerSO-10 packages.Features Automatic burst mode for very low consumption in stand-by conditions (less than 500mW); Integrated high voltage start-up current source; Overload and short circuit control; Over-voltage protection at 18V; Over-temperature shutdown; Under-voltage protection; Current mode control with adjustable drain current limitation; Externally set switching frequency, up to 300kHz.

主要特徵

  • Automatic burst mode for very low consumption in stand-by conditions (less than 500mW);
  • Integrated high voltage start-up current source;
  • Overload and short circuit control;
  • Over-voltage protection at 18V;
  • Over-temperature shutdown;
  • Under-voltage protection;
  • Current mode control with adjustable drain current limitation;
  • Externally set switching frequency, up to 300kHz.

常見問題解答

What is VIPER53ESP?

The VIPER53ESP is a high-voltage converter IC (integrated circuit) designed by STMicroelectronics. It is specifically designed for offline power supplies in a wide range of applications such as home appliances, industrial systems, and consumer electronics.

How Does VIPER53ESP Work?

The VIPER53ESP operates as a high-voltage converter that integrates a PWM controller and a power MOSFET. It provides a cost-effective and compact solution for offline power supply designs with high efficiency and low standby power consumption. The IC also includes a range of protection features for enhanced reliability and safety.

How Many Pins does VIPER53ESP have and What are the Functions of the Pinout Configuration?

The VIPER53ESP is available in various package options, such as DIP (Dual Inline Package) and SOIC (Small Outline Integrated Circuit). The pinout configuration typically includes:

  • VCC: IC supply voltage pin.
  • GND: Ground pin.
  • CS: Current sense pin for feedback and control.
  • FB: Feedback pin for voltage regulation.
  • COMP: Compensation pin for loop stability.
  • UVLO: Under-voltage lockout pin for protection.
  • SD: Shutdown pin for enabling/disabling the IC.
  • SENSE: Sense pin for output voltage sensing and regulation.
  • DD: Drain pin for the internal power MOSFET.

What are the Pros and Cons of VIPER53ESP?

Pros:

  • Integrated Solution: Combines PWM controller and power MOSFET, reducing external component count.
  • Efficiency: Provides high efficiency in offline power supply applications.
  • Protection Features: Includes a range of protection features such as overvoltage and overcurrent protection.
  • Compact Design: Space-efficient package options for flexible PCB layout.
  • Wide Application Range: Suitable for various offline power supply designs in consumer and industrial electronics.

Cons:

  • Complexity: May require proper design considerations for loop stability and EMI (Electromagnetic Interference) compliance.
  • Thermal Management: Careful attention to thermal dissipation may be needed, especially in high-power applications.
  • External Components: Some external components may be required for specific application requirements.

Are There Any Equivalents/Alternatives to VIPER53ESP for Recommendation?

Alternatives to the VIPER53ESP include the LNK306 from Power Integrations and the FSDM0365RN from Fairchild Semiconductor. These ICs offer similar functionality for offline power supply applications.
