Texas Instruments LM5155EVM-FLY Controller Evaluation Module showcases the features and performance of the LM5155 as a wide input non-synchronous flyback controller. The standard configuration is created to offer a regulated output of 5V at 4A from an input of 18V to 36V, switching at 250kHz.
This evaluation module is created for ease of configuration, allowing the user to evaluate many different applications on the same module. The PCB is two layers with components populated only on one side. Functionality comprises programmable slope compensation, programmable cycle-by-cycle current limit, adjustable soft-start, hiccup mode short-circuit protection, and programmable line under-voltage lockout.
The device features an input voltage range between 18V to 36V; isolated output voltage 5V at 4A; and switching frequency of 250kHz. The device is a two-layer PCB construction with a single-sided component population; and has hiccup mode short circuit protection.
