Off-line high voltage converters

Features

■ 800 V avalanche rugged power section

DIP-7

■ PWM operation with frequency jittering for low

EMI

■ Operating frequency:

– 60 kHz for L type

– 115 kHz for H type

Description

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

rugged power section, a PWM control, two levels

of over current protection, over voltage and

overload protections, hysteretic thermal

protection, soft-start and safe auto-restart after

any fault condition removal. Burst mode operation

and device very low consumption helps to meet

the standby energy saving regulations.

■ Standby power < 50 mW at 265 Vac

■ Limiting current with adjustable set point

■ Adjustable and accurate over voltage

protection

■ On-board soft-start

■ Safe auto-restart after a fault condition

■ Hysteretic thermal shutdown

Advance frequency jittering reduces EMI filter

cost. Brown-out function is embedded into the

high voltage start-up.

Application

■ Adapters for PDA, camcorders, shavers,

Figure 1. Typical topology

cellular phones, videogames

■ Auxiliary power supply for LCD/PDP TV,

monitors, Audio systems, computer, industrial

■ SMPS for set-top boxes, DVD players and

recorders, white goods.
