MURATA MYRNP PicoBK™ DC-DC Converter | New Product Brief

September 21, 2021 by Mouser Electronics

This New Product Brief (NPB) is part of a video series highlighting the features, applications, and technical specs of newly-released products.


Murata Electronics MYRNP PicoBK™ are small coil-integrated negative voltage DC-to-DC converters IC.

Integrating the coil with the DC-to-DC converter simplifies the circuit board layout and minimizes potential noise interference. This solution offers the switching methods of the MYRNP series to maintain a stable output voltage even when the input voltage fluctuates while also supporting a larger output current.  

These DC-to-DC converters offer a 2.7V to 5.5V input voltage range, -1.2V to 6V output voltage range, a 2.5 megahertz oscillation frequency, and a 300 milliamp output current.

The PWM-controlled MYRNP050030W21RA can be used with applications where low noise is important, and the PWM- and PFM- automatic switching-controlled MYRNP050030B21RA is ideal for applications where high efficiency at light load current and low noise at high load current is important.
