VIPER38
Features
- 800 V avalanche-rugged power MOSFET allowing ultra wide range input Vac to be achieved
- Embedded HV start-up and sense FET
- PWM current-mode controller
- OCP with selectable threshold (IDlim) and 2nd
OCP with higher value (IDMAX) to protect the IC from transformer saturation or short-circuit of the secondary diode
- 30 m W no-load consumption at 230 Vac
- Two operating frequencies:
- 60 k Hz (L type) or 115 k Hz (H type)
- Jittered frequency reduces the EMI
- Extra power timer (EPT) blanks the overload current for few seconds
- production data
- Output overvoltage protection with tight tolerance and digital noise filter
- Soft-start reduces the stress during startup and increases IC lifetime
- Automatic restart after a fault condition
- Thermal shutdown increases system reliability and IC lifetime
Applications
- Auxiliary power supply for consumer and home equipment
- Power supply for energy meters and data concentrators
- Adapters
