Working Principles

The VIPER15HDTR is a high-voltage converter that utilizes a switching regulator to efficiently convert input voltage to the desired output voltage. It incorporates an integrated high-voltage startup circuit, error amplifier, and various protection features.

The device operates by controlling the power MOSFET switch based on feedback from the output voltage. The error amplifier compares the actual output voltage with the desired voltage set by the feedback pin (FB). Based on this comparison, the control circuit adjusts the duty cycle of the power MOSFET to regulate the output voltage.

The VIPER15HDTR also includes comprehensive protection features such as overvoltage, undervoltage, overcurrent, and thermal shutdown protection. These safeguards ensure safe operation and protect the device and surrounding components from damage.
