Product Summary

The TEA1733T is a low cost Switched Mode Power Supply (SMPS) controller IC, which is intended for flyback topologies. The TEA1733T operates in fixed frequency mode. To reduce ElectroMagnetic Interference (EMI), frequency jitter has been implemented. For Continuous Conduction Mode (CCM) operation, slope compensation is integrated.

Parametrics

TEA1733T absolute maximum ratings: (1)supply voltage continuous: -0.4 to +30 V; (2)voltage on pin VINSENSE: -0.4 to +5.5 V; (3)voltage on pin PROTECT: -0.4 to +5 V; (4)voltage on pin CTRL: -0.4 to +5 V; (5)input/output voltage on pin OPTIMER: -0.4 to +5 V; (6)voltage on pin ISENSE: -0.4 to +5 V; (7)input current on pin VINSENSE: -1 to +1 mA; (8)input current on pin PROTECT: -1 to +1 mA; (9)current on pin CTRL: -3 0 mA; (10)current on pin ISENSE: -10 to +1 mA; (11)current on pin DRIVER: -0.4 to +1 A; (12)total power dissipation: 0.5 W; (13)storage temperature: -55 to +150 ℃; (14)junction temperature: -40 to +150 ℃.

Features

TEA1733T features: (1)SMPS controller IC enabling low cost applications; (2)Large input voltage range (12 V to 30 V); (3)Very low supply current during start-up and restart (typically 10 mA); (4)Low supply current during normal operation (typically 0.5 mA without load); (5)Overpower or high/low line compensation; (6)Adjustable overpower time-out; (7)Adjustable overpower restart timer; (8)Fixed switching frequency with frequency jitter to reduce EMI; (9)Frequency reduction with fixed minimum peak current at low power operation to maintain high efficiency at low output power levels; (10)Slope compensation for CCM operation.
