Product overview

Description

The device is a high voltage converter smartly integrating a 1050 V avalanche-rugged power section, with a PWM current mode control. The 1050 V-BV power MOSFET allows to extend input voltage range, and reduce the size of the DRAIN snubber circuit. This IC meets the most stringent energy-saving standards as it has very low consumption and operates in burst mode under light load.

The integrated HV startup, sense-FET, error amplifier and oscillator with jitter allow a complete application to be designed with the minimum number of components.

The VIPer26K supports the most common SMPS topologies such as: isolated flyback with optocoupler, primary-side regulation, non-isolated flyback with resistive feedback, buck, and buck boost.

  • All features

    • 1050 V avalanche-rugged power MOSFET
    • allowing ultra-wide VAC input range to be covered
    • Embedded HV startup and sense-FET
    • Current mode PWM controller
    • Drain current limit protection:
    • -500 mA (VIPER265K)
    • -700 mA (VIPER267K)
    • Jittered switching frequency reduces the EMI filter cost: 60 kHz ± 4kHz
    • Standby power < 30 mW at 230 VAC
    • Embedded E/A with 3.3 V reference
    • Safe auto-restart after a fault condition
    • Hysteretic thermal shutdown
    • Built-in soft-start for improved system reliability
