Product overview

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. 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.

All features
800 V avalanche-rugged power MOSFET allowing ultra wide range input V_acto be achieved

PWM operation with adjustable limiting current

30 mW standby power at 265 V_ac

Operating frequency:

Frequency jittering for low EMC

Output overvoltage protection
High primary current protection (2nd OCP)

Input undervoltage setting (brownout)

Onboard soft-start

Safe auto-restart after a fault condition

Hysteretic thermal shutdown
