Product Summary

The TDA4605 is a control circuit for switch mode power supplies using MOS transistor. The IC TDA4605 controls the MOSPower Transistor and performs all necessary regulation and monitoring functions in free running flyback converters. Since good load regulation of the TDA4605 over a wide load range is attained, this IC is particularly suitable for Consumeras well as IndustrialPower Supplies. Alternative source of the TDA4605 is also available from SIEMENS Semiconductors Consumer Electronics A.G.

Parametrics

TDA4605 absolute maximum ratings: (1)Tj Junction Temperature (autom. thermal disjunction): +125 ℃; (2)Tstg Storage Temperature: -40, +125 ℃; (3)Supply Voltage, Pin 1: -0.3, +3 V.

Features

TDA4605 features: (1)Fold-back characteristic provides overload Protection for external diodes; (2)Burst operation under short-cir cuit and no loadconditions; (3)Loop error protection; (4)Switch-off in case of too low line voltage(under voltage switch-off); (5)Line voltage compensation of over loadpoint; (6)soft-start for smooth start-up; (7)Chip over-temperature protection(thermal shutdown) On-chip parasitic transformer os cillationsuppression circuitry; (8)Decrease of regulated voltage for low power consumption.
