Product Summary

The TDA4605-3 is a control IC for switched-mode power supplies using MOS-transistor. It controls the MOS-power transistor and performs all necessary control and protection functions in free running flyback converters. Because of the fact that a wide load range is achieved, the TDA4605-3 is applicable for consumer as well as industrial power supplies.

Parametrics

TDA4605-3 absolute maxing ratings: (1)Voltages pin 1 V1: MIN=-0.3V, MAX=3V; pin 2 V2: MIN=-0.3V; pin 3 V3: MIN=-0.3V; pin 5 V5: MIN=-0.3V, MAX=V6V; pin 6 V6: MIN=-0.3V, MAX=20V; pin 7 V7: MIN=-0.3V; (2)Currents pin 1 I1: MAX=3mA; pin 2 I2: MAX=3mA; pin 3 I3: MAX=3mA; pin 4 I4: MIN=-1.5A; pin 5 I5: MIN=-0.5A, MAX=1.5A; pin 6 I6: MAX=0.5A; pin 7 I7: MAX=3mA; pin 8 I8: MIN=-5mA, MAX=3mA; (3)Junction temperature Tj: MAX=125℃; (4)Storage temperature Tstg: MIN=-40℃, MAX=125℃.

Features

TDA4605-3 features: (1)Fold-back characteristics provides overload protection for external components; (2)Burst operation under secondary short-circuit condition implemented; (3)Protection against open or a short of the control loop; (4)Switch-off if line voltage is too low (undervoltage switch-off); (5)Line voltage depending compensation of fold-back point; (6)Soft-start for quiet start-up without noise generated by the transformer; (7)Chip-over temperature protection implemented(thermal shutdown); (8)On-chip ringing suppression circuit against parasitic oscillations of the transformer; (9)AGC-voltage reduction at low load.
