VIPER17 - HV switching regulator

Description

The device is an off-line converter with an 800 V rugged power section, a PWM control, two levels of overcurrent protection, overvoltage and overload protections, hysteresis thermal protection, soft-start and safe auto-restart after any fault condition removal.

Features

  • Advance frequency jittering reduces EMI filter.
  • 800 V avalanche rugged power section.
  • PWM operation with frequency jittering for low EMI.
  • Operating frequency:  60 kHz for L type cost. Brown-out function protects the switch mode power supply when the rectified input voltage level is below the normal minimum level specified for the system. The high voltage startup circuit is embedded in the device.  115 kHz for H type.
  • Standby power < 30 mW at 265 VAC Table 1: Device su.
