Figure 1. Typical application
• Standby power < 30 mW at 230 V_AC
• Limiting current with adjustable set point
• On-board soft-start
• Safe auto-restart after a fault condition
• Hysteretic thermal shutdown
Application
• Replacement of capacitive power supply
• Auxiliary power supply for appliances,
• Power metering
• LED drivers
Description
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
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. It is able to power itself directly from the
rectified mains, eliminating the need for an
auxiliary bias winding. 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.
• No need of auxiliary winding for low power
