VIPER37

VIPerPlus family: fixed frequency offline converter

Features

■ 800 V avalanche rugged power section

■ PWM operation with adjustable limiting current

■ 30 mW standby power at 265 Vac

SDIP10

■ Operating frequency:

– 60 kHz for L type

– 115 kHz for H type

Description

This device is an offline converter with an 800 V

rugged power section, a PWM control, two levels

of overcurrent protection, overvoltage and

overload protection, hysteretic thermal protection,

soft-start, and safe auto-restart after the removal

of any fault condition. Burst mode operation and

very low device consumption help to meet the

standby energy saving regulations.

■ Frequency jittering for low EMC

■ Output overvoltage protection

■ High primary current protection (2^ndOCP)

■ Input undervoltage setting (brownout)

■ Onboard soft-start

■ Safe auto-restart after a fault condition

■ Hysteretic thermal shutdown

Advance frequency jittering reduces EMI filter

costs. Brownout 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.

Applications

■ SMPS for set-top boxes, DVD players and

recorders, white goods

■ Auxiliary power supply for consumer and home

equipment
