VIPER28HDTR

VIPER28HDTR is a peak power high-voltage converter - VIPer Plus in a 16 pin NSOIC package. The device is a high-voltage converter that smartly integrates an 800V rugged power MOSFET with PWM current-mode control. This IC is capable of meeting more stringent energy saving standards as it has very low consumption and operates in burst mode under light load. The device features an adjustable extra power timer (EPT) that enables the IC to sustain overload conditions for a few seconds. The integrated HV startup, sense FET and oscillator with jitter allow the advantage of using minimal components in the application. The device features high-level protections like dual-level OCP, output overvoltage, short-circuit, and thermal shutdown with hysteresis. After the removal of a fault condition, the IC is automatically restarted. Applications include auxiliary power supplies for consumer and home equipment, power supplies for energy meters and data concentrators, and AC-DC adapters.

• 800V avalanche-rugged power MOSFET allowing achieving ultra wide-range input V AC
• Embedded HV startup and sense FET
• PWM current-mode controller
• OCP with selectable IDlim & 2nd OCP(IDMAX) for IC protection from transformer saturation/diode short
• 30mW no-load consumption at 230V AC
• Jittered frequency reduces the EMI
• Extra power timer (EPT) blanks the overload current for few seconds
• Output overvoltage protection with tight tolerance and digital noise filter
• Soft-start reduces the stress during startup and increases IC lifetime
• Thermal shutdown increases system reliability and IC lifetime
