So, what is the value proposition with the LM27403: The wide input voltage range can be used as a high-performance voltage regulator in 12 V, 5 V, and 3.3 V systems. The temperature-compensated current limit can reduce inductor cost and size while also improving reliability. The LM27403 also has a higher switching frequency and a low minimum on-time, which enables a small solution size and input voltage/Output voltage scalability. The 15 ns dead time provides higher efficiency through lower power consumption. Finally, fast transient response can also be achieved with the 6 MHz error amplifier bandwidth. This is a fully functional, full featured device that provides a great deal of value to the end customer.
