VIPER0PHDTR General Description

The device is a high-voltage converter that smartly integrates an 800 V avalanche rugged power MOSFET with PWM current-mode control. The power MOSFET with 800 V breakdown voltage allows extended input voltage range to be applied, as well as to reduce the size of the DRAIN snubber circuit. This IC is capable of meeting the most stringent energy-saving standards as it has very low consumption and operates in pulse frequency modulation under light load. The zero-power mode (ZPM) feature enables the IC to work in an idle state, where the system is totally shutdown. An MCU can be easily connected to the IC for smart ZPM management and it can be supplied by the IC itself during the idle state. The design of flyback, buck and buck boost converters is supported. The integrated HV startup, sense FET, error amplifier and oscillator with jitter allow a complete application to be designed with a minimum component count. In flyback non isolated topology, a negative output voltage is easily set thanks to the integrated error amplifier with separate ground.7 W dual output offline flyback converter for ho.12 V - 0.6 A flyback isolated converter using VI.7 W dual output flyback converter with standby m.15 V, 0.15 A buck converter using VIPer™ P.

Key Features

Smart stand-by architecture using the zero-power mode (ZPM)
ZPM management by MCU easily realizable
800 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 (OCP)
Wide supply voltage range: 4.5 V to 30 V
Self-supply option allows to remove the auxiliary winding or bias components
Minimized system input power consumption:
- Less than 4 mW @ 230 V_AC in ZPM
- Less than 10 mW @ 230 V_AC in no-load condition
- Less than 400 mW @ 230 V_AC with 250 mW load
Jittered switching frequency reduces the EMI filter cost
Embedded E/A with 1.2 V reference and separate ground for easy negative voltage setting
Protections with automatic restart: overload/short circuit (OLP), max. duty cycle counter, V_CC clamp
Pulse-skip protection to prevent flux-runaway
Embedded thermal shutdown
Built in soft start for improved system reliability
