SLVAFK5A December 2023 – February 2024 LM5177
To verify the thermal stability of the EVM with parallel operation and load sharing, thermal images (Figure 4-11 to Figure 4-18) are taken of EVM for normal and extreme load conditions under different LM5177 converter topologies. The maximum operating temperature of LM5177 is 120 degrees Celsius. The results show that the maximum load current capability in boost mode is limit to 12 A because of the peak current limiter, and have a high temperature under extreme load (12 A) conditions compared to the buck and buck-boost modes.
