产品概述

描述

The VIPER26 device is a smart high voltage converter that integrates an 800 V avalanche-rugged power MOSFET with PWM current mode control. The power MOSFET with 800 V breakdown voltage allows an extended input voltage range to be applied, as well as the size of the DRAIN snubber circuit to be reduced. This IC meets the most stringent energy-saving standards with very low consumption and burst mode operation under light load.
The design of flyback, buck and buck boost converters is supported. The integrated HV startup, sense-FET, error amplifier and oscillator with jitter allow complete application designs with a minimum number of components.

所有功能
800 V avalanche rugged power MOSFET allowing wide range V_AC input range to be covered

Embedded HV startup and sense-FET

Current mode PWM controller

Minimized system input power consumption:

Less than 30 mW @ 230 V_AC in no-load condition

Less than 400 mW @ 230 V_AC with 250 mW load

Limiting current with adjustable set point

Jittered switching frequency to reduce the EMI filter cost:

60 kHz ±4 kHz (L type)

115 kHz ±8 kHz (H type)

Embedded error amplifier

Hysteretic thermal shutdown

Built-in soft-start for improved system reliability

Protections with automatic restart: overload/short-circuit (OLP), feedback loop disconnection
