VIPER317LDTR General Description

The VIPER31 device is a high-voltage converter that smartly integrates an 800 V avalanche rugged power MOSFET with PWM current-mode control.The 800 V breakdown allows extended input voltage range to be applied, as well as to reduce the size of the DRAIN snubber circuit. The IC can meet the most stringent energy-saving standards as it has very low consumption and operates in pulse frequency modulation at light load. Overvoltage and undervoltage protections with separate and settable intervention thresholds are available at OVP and UVP pins respectively. UVP can also be used as a disabling input for the entire SMPS, with ultra-low residual input power consumption. Integrated HV startup, sense FET, error amplifier and oscillator with frequency jitter allow a complete application to be designed with a minimum component count.

Key Features

800 V avalanche-rugged power MOSFET (4.5 Ω max. R_DS(on))
Embedded HV startup and sense FET
Current mode PWM controller
Drain current limit protection (OCP)
- 710 mA (VIPER317)
- 850 mA (VIPER318)
- 990 mA (VIPER319)
Wide supply voltage range: 4.5 V to 30 V
Ultra-low input power consumption:
- < 10 mW @ 230 VAC in no-load;
- < 400 mW @ 230 VAC, 250mW output load
Jittered switching frequency reduces the EMI filter cost:
- 30 kHz ±7% (type X)
- 60 kHz ±7% (type L)
- 132 kHz ±7% (type H)
Embedded E/A with 1.2 V reference
Built-in soft-start for improved system reliability
Embedded protections with automatic restart
