AN10981
Overview
The TEA1738 is a fixed frequency flyback controller that can be used for Discontinuous Conduction Mode (DCM) as well as Continuous Conduction Mode (CCM). 1.1 Scope This application note describes the functionality of the TEA1738 series. Fixed-frequency flyback fundamentals and calculation of transformer and other large signal parts are not dealt with in this application note.
- SMPS controller IC enabling low cost applications Large input voltage range (12 V to 30 V, 35 V peak allowed for 100 ms) Very low supply current during start and restart (typically 10 μA) Low supply current during normal operation (typically 500 μA, no load) Overpower compensation (high/low line compensation) Adjustable overpower
