VIPER26

Fixed frequency VIPerTM plus family

Features

■ 800 V avalanche rugged power section

■ PWM operation with frequency jittering for low

EMI

■ Operating frequency:

– 60 kHz for L type

– 115 kHz for H type

■ Standby power < 50 mW at 265 VAC

■ Limiting current with adjustable set point

■ On-board soft-start

■ Safe auto-restart after a fault condition

■ Hysteretic thermal shutdown

Application

■ Auxiliary power supply for appliances

■ Power metering

■ LED drivers

■ SMPS for set-top boxes, DVD players and

recorders

Description

The device is an off-line converter with an 800 V

avalanche ruggedness power section, a PWM

controller, user defined overcurrent limit,

protection against feedback network

disconnection, hysteretic thermal protection, soft

start up and safe auto restart after any fault

condition.

Advance frequency jittering reduces EMI filter

cost. Burst mode operation and the devices very

low consumption both help to meet the standard

set by energy saving regulations.
