Figure 1. The LTM8074 uses Silent Switcher architecture for a complete low noise solution in a tiny package.

Crowded application boards leave little space for high performance DC-to-DC POL converters. Furthermore, electromagnetic interference (EMI) is a significant concern at high component densities, limiting the field of acceptable power solutions. The LTM8074 µModule regulator easily meets these limiting factors. It
