Texas Instruments LM5155EVM-FLY Controller Evaluation Module (EVM)

Texas Instruments LM5155EVM-FLY Controller Evaluation Module (EVM) showcases the features and performance of the LM5155 as a wide input non-synchronous flyback controller. The standard configuration is designed to provide a regulated output of 5V at 4A from an input of 18V to 36V, switching at 250kHz. The Texas Instruments LM5155EVM-FLY is designed for easy configuration, enabling users to evaluate many different applications on the same module. The PCB is two layers with components populated only on one side. Functionality includes programmable slope compensation, adjustable soft-start, programmable cycle-by-cycle current limit, hiccup mode short-circuit protection, and programmable line under-voltage lockout.

Features

  • 18V to 36V input voltage range 
  • Isolated output voltage of 5V at 4A
  • Switching frequency of 250kHz
  • Two-layer PCB with a single-sided component population
  • Hiccup mode short circuit protection
