Compact, single-chip MPS monolithic power modules for DC-DC applications

Mouser now stocks the MPM from Monolithic Power Systems. Providing superior performance and inherent reliability by eliminating unnecessary assembly steps and minimising external components, the MPM family comprises integrated DC-DC solutions that consist of a monolithic regulator, passive components, and a mould compound all in a single chip. Based on their innovative single-step assembly process, these step-down DC-DC converters offer circuit simplicity for ease of design; are highly efficient; yield superior noise, ripple, and transient performance; and are available in a compact module form factor that is up to 50 percent smaller than competing solutions. The MPS modules are high-frequency, synchronous, rectified, step-down, switch-mode converters with built-in power MOSFETs and integrated inductors. Each of the modules can regulate a continuous output current to input voltage with excellent load and line regulation results. The modules operate on a switching frequency of up to 2.4MHz to achieve a fast load transient response, and feature a wide operating input range of up to 36V. The devices also include a variety of protective features including over-current protection and thermal shut down. Packing massive power into a tiny package, all modules within the MPM family are designed with a small surface-mount footprint that is easy to use and rework due to their standard QFN packaging. This packaging not only eliminates some of the disadvantages that are typically associated with BGA or NDY packages, but it also makes the modules more cost effective for the designer and improves overall time-to-market. The modules are available now from Mouser Electronics in a variety of QFN packages with SMD/SMT mounting. All modules in the family are lead-free, halogen free and RoHS-compliant, and are ideally suited toward a broad array of space-constraint, DC-DC applications, including those in industrial products and controls, IoT devices, low-voltage I/O power solutions, optical modules, and medical devices.
