Description

The UC1843BEVM-CVAL uses the UC1843A-SP, INA901-SP, LM139AQML-SP, and UC1901-SP to create an isolated feedback flyback with current sensing and over current flags. The UC1843A-SP is used to switch the low side MOSFET of the flyback converter and provide voltage and current to the output. The UC1901-SP senses the output voltage and completes the loop for the isolated feedback. The INA901-SP senses the input current which is provided to the LM139AQML-SP to create an over current flag.

Features
  • PWM control using UC1843B-SP
  • Over current comparison using LM139AQML-SP
  • Current sensing using INA901-SP
