VIPER37HE Typical application Circuitry

VIPER37HE

The VIPer37HE is an offline high voltage converter from Microelectronics. This fixed-frequency device integrates an 800V avalanche-rugged power MOS FET. The device also allows the design of an ultra-wide range SMPS (Switched-Mode Power Supply) suitable for input voltages varying from 85VAC up to 305VAC, maintaining the energy-saving performance.

1. Drain Connection: Join the transformer's primary winding to the Drain connector (pin 1). This pin is connected to the integrated power MOS FET, which switches the current through the transformer's primary winding.

2. Ground Connection: The ground (GND) pin (pin 2) serves as the reference for the device's control circuitry and the source of the internal power MOS FET. It should be connected to the negative rail of the auxiliary voltage for the chip.

3. VDD Connection: The VDD pin (pin 3) is the power supply pin for the VIPer37HE. It should be connected to the positive rail of the auxiliary voltage, typically derived from a secondary winding on the transformer.

4. Feedback and Control: The control pin (pin 4) receives the feedback from the optocoupler in the secondary side of the power supply, which indicates the output voltage level. This pin should be connected to the midpoint of a resistor divider between the output of the optocoupler and ground. This feedback allows the VIPer37HE to regulate the output voltage.

5. Source Connection: The source (S) pin (pin 5) is internally connected to the source of the power MOS FET and provides a return path for the current flowing through the primary winding of the transformer.

The VIPer37HE is a robust and efficient solution for offline power supplies, offering a wide range of features that simplify the design and improve the performance of the SMPS. For optimal performance, adhere to good practices for PCB layout, grounding, and power supply design as detailed in the VIPer37HE data sheet.
