General Description
Application Circuit The application circuit shows a flyback converter for video recorders with an output power rating of 70 W.
The circuit is designed as a wide-range power supply for AC-line voltages of 180 to 264 V.
The AC-input voltage is rectified by the bridge rectifier GR1 and smoothed by C1 .
Key Features
- q Fold-back characteristics provides overload protection for q q q q q q q q external components Burst operation under secondary short-circuit condition implemented Protection against open or a short of the control loop Switch-off if line voltage is too low (undervoltage switch-off) Line voltage depending compensation of fold-back point Soft-start for quiet start-up without noise generated by the transformer Chip-over temperature protection implemented (thermal shutdown) On-chip ringing suppres.
