Description
GND VDD CONT FB
Features
800 V avalanche rugged power section
The device is an off-line converter with an 800 V
rugged power section, a PWM control, two levels
of overcurrent protection, overvoltage and
overload protections, hysteresis thermal
protection, soft-start and safe auto-restart after
any fault condition removal. The burst mode
operation and the device’s very low consumption
meet the standby energy saving regulations.
PWM operation with frequency jittering for low
EMI
Operating frequency:
– 60 kHz for L type
– 115 kHz for H type
Standby power < 30 mW at 265 Vac
Advance frequency jittering reduces EMI filter
cost. Brown-out 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 start-up circuit is
embedded in the device.
Limiting current with adjustable set point
Adjustable and accurate overvoltage
protection
