Sanken's MPM (Micro Power Module) series is a hybrid IC family that incorporates a non-isolated buck DC-DC converter circuit with an inductor in a single-fully-molded package. The ICs enable designing a power supply circuit with fewer external components. The products are ideal for the replacement of a discrete DC-DC converter IC, such as a local regulator on various systems to lower component count and save space.
MPM8x: 2 A Non-Isolated Step-Down DC/DC Converter Modules
MPM01: DC-to-DC Converter Module
MPM04: DC-to-DC Converter Module
Features
- Fewer external components required
- IC operates just by connecting an input smoothing capacitor, an output smoothing capacitor, and output voltage setup resistance
- Built-in inductor
- Built-in power inductor eliminates requirement to evaluate and select the inductor separately
- Sanken proprietary fully-molded and integrated package
- The full-mold package allows a screw clamp connection to a heatsink. Depending on an output voltage setup and load conditions, the IC can be operated without a heatsink

- Wide-input voltage range, high-efficiency
- Input voltage range of 9 VDC to 40 V for MPM01/04 and 8 to 30 V for MPM80 series. The efficiency is 88 to 95% (typ)
- Various protection functions
- Protection functions such as overcurrent protection (OCP), overvoltage protection (OVP), and thermal shutdown (TSD) are built-in
- Built-in phase compensation
- Eliminates the requirement for an external constant clock; the reference voltage of the IC output has 0.5 V ±2% accuracy, and is a control-drive-type phase compensation
