Overview
Control IC for Switched-Mode Power Supplies using MOS-Transistor TDA 4605-3 Bipolar IC 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 suppression circuit against parasitic oscillations of the transformer AGC-voltage reduction at low load P-D...
