Monolithic Power Systems’ (MPS) Monolithic Power Modules (MPMs) are available from Mouser Electronics.

Offering strong performance and reliability by eliminating unnecessary assembly steps and minimising external components, the MPM family comprises integrated DC/DC products that consist of a monolithic regulator, passive components and a mould compound in a single chip.

Based on MPS’s single-step assembly process, these step-down DC/DC converters offer circuit simplicity for ease of design; are efficient; yield strong noise, ripple and transient performance; and are available in a compact module form factor that is up to half the size of other products on the market.

The MPMs 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 good 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 such as 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 MPS’s standard QFN packaging. This packaging not only eliminates some of the disadvantages typically associated with BGA or NDY packages but makes the modules more cost-effective for the designer and improves overall time to market.

The MPMs are available 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 suited to an array of space-constraint DC/DC applications, including those in industrial products and controls, Internet of Things (IoT) devices, low-voltage I/O power products, optical modules and medical devices.
