Comparison

In summary, the advantages of the MAX6518UKP095 include its high efficiency, compact size, and wide range of load current support. It offers a dropout voltage of less than 1.0V, which helps to minimize power loss. The device also operates at a high switching frequency of up to 300kHz, allowing for the use of smaller surface-mount inductors. One of its notable disadvantages is the limited options for fixed output voltages, as it only provides 5V, 3.3V, and 3V options.

• High efficiency over a wide range of load currents
• Compact size and use of miniature external components
• Low quiescent and shutdown supply current consumption
• Wide input voltage support
• Current-limited control scheme for improved safety
• High switching frequency for smaller inductor size

• Limited options for fixed output voltages
