Power Modules Boost Power Density While Speeding Time-to-Market (Download)

Engineers have many options when designing power stages, from low-dropout (LDO) regulators to switching power supplies. The former provide low noise and ripple for sensitive circuit elements, but the latter deliver the efficiency and power density often required to remain competitive in today’s marketplace.

Unfortunately, switching power supplies require bulky inductors or transformers that typically require shielding, and they can be difficult to fit within the mechanical constraints of your design. In addition, inductors and transformers may be difficult to source. As an alternative, you can choose a power module that integrates the required inductor or transformer within the switching-regulator package.
