Texas Instruments LM5169FEVM Evaluation Module

Texas Instruments LM5169FEVM Evaluation Module implements the LM5169FNGUR to create a regulated 10V output capable of providing a 300mA load on the primary side of the transformer with a switching frequency of 750kHz. The secondary side of the transformer supplies a reflected output of 10V, furnishing up to 300mA. The TI LM5169FNGUR is a synchronous buck converter with integrated power MOSFETs, a wide input voltage range, overcurrent protection, and precision enable.

Features

  • Wide input voltage range from 20V to 115V
