New DC/DC Converters Offer 50 Percent Smaller Footprint

Murata unveiled the MYWGC series from the MonoBK™ DC/DC converter family. The new point-of-load (POL) modules offer a 50-percent smaller footprint than competing solutions and set new standards in size, efficiency and performance. The highly integrated, multi-output DC/DC converters leverage Murata’s core technology advantages in power module development, advanced 3D integrated packaging and passive component expertise.

The MonoBK™ MYWGC series are 4-channel DC/DC converters that integrate all passive components, including inductors, into a tiny form factor of 9.3 mm × 9.0 mm × 2.9 mm (L × W × H). The products feature an input voltage range of 2.8–5.5 V and programmable outputs of 0.4–3.58 V up to 3.0 amps. Most applications will require few external components.

Due to the unique packaging process, the module has an outstanding thermal performance that can support a wide temperature range of –40 to +105 °C. Based on a fixed-frequency synchronous buck converter switching topology, this high-efficiency POL module features on/off control and power-good signal out.

The first product in the series, the MYWGC3R53FFW92RAE, features protections for over-current (OCP), over-voltage (OVP), under-voltage (UVP) and over-temperature (OTP). Target power applications include FPGAs, CPUs and datacom/telecom systems. The product is sampling now, and mass production is scheduled for Q2 2020.
