Overview
Siemens Power Hybrid for SMPS Preliminary Data SPH 4692 Bipolar IC Features q Fold-back characteristics provides overload protection for 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 P-DIP-18-4 Power MOSFET q VDS = 600 V q R DS ON = 3.
