The TMI97153B is a monolithic flyback dc-dc converter with a 160V power switch that targets isolated 13W PoE applications. It supports both primary-side regulated flyback applications. TMI97153B uses fixed peak current and variable frequency discontinuous conduction mode (DCM) to regulate constant output voltage. The primaryside regulation without opto-coupler feedback in flyback mode simplifies the design and saves BOM cost. A 160V integrated power MOSFET optimizes the device for various wide voltage applications. The TMI97153B protection features include overload protection, over-voltage protection, opencircuit protection, and thermal shutdown. The TMI97153B is available in ESOP8 package.
