EMI is one of those dirty words (okay, it’s an acronym) in board and system design. Some designers just keep their fingers crossed and hope for the best, while others spend considerable time making sure that EMI effects don’t have a negative impact on their board or system,
One way to streamline this portion of the design process is to take advantage of Maxim’s Himalaya power modules. These solutions, which comply with CISPR 22 and EN 55022, are suited for a host of general-purpose applications, such as industrial, building and factory automation, communications, and consumer electronics.
The Himalaya power modules integrate most of the components needed for a power supply into one compact package. That includes a synchronous switching regulator IC, an inductor, resistors, and capacitors. The result is an efficient, fully integrated solution that complies with EMI requirements.
While modules may suit many needs, designers have the option to migrate, as needed, between modules and ICs to tradeoff cost, size, and ease of use. The high-efficiency, low-profile, wide input voltage, step-down DC-DC power modules are available in a system-in-package (SiP) or ultra-small micro system level IC (uSLIC). These ready-made, reliable, easy-to-use modules save PCB space and reduce design time for 5-, 12-, 24-, 36-, 48-, and 60-V rails. The devices that make up the family include the MAXM15462, MAXM17532, MAXM17574, MAXM17575, and MAXM17761.
