TEA1733T/N1,118

交流/直流转换器 SW Mode Power Supply Controller 8-Pin GreenChip SMPS control IC

General description TEA1733T/N1,118

The TEA1738(L) is a low cost Switched Mode Power Supply (SMPS) controller IC

intended for flyback topologies. The TEA1738(L) operates in peak current and frequency

control mode. Frequency jitter has been implemented to reduce ElectroMagnetic

Interference (EMI). Slope compensation is integrated for Continuous Conduction Mode

(CCM) operation.

 Features TEA1733T/N1,118

„ SMPS controller IC enabling low-cost applications

„ Large input voltage range (12 V to 30 V)
