Panasonic NN31000x PSiP Power Supply in Package DC/DC Converter

 

Overview

Panasonic NN31000x PSiP Power Supply in Package DC/DC Converter is a synchronous DC-DC step down regulator (1-ch), Power Supply in Package (PSiP), which integrates a Controller IC that employs a hysteretic control system, two Power MOSFETs, an Inductor and Capacitors into a single 8.5 x 7.5 x 4.7mm QFN package. The easiness of mounting PSiP onto a Printed Circuit Board (PCB), a very small footprint and a highly reduced number of external components, offers very compact and simplified solutions for applications requiring point-of-load design. The number of external components have been reduced to only input/output capacitor, slow start capacitor and feedback resistors. Furthermore, for applications requiring an output voltage of 1.0 V / 3.3 V, the external feedback resistors can be eliminated, resulting in even a smaller footprint. The PSiP achieves efficiencies of greater than 95 % with very good power dissipation capabilities.
​With a unique arrangement structure, Panasonic's Power Supply in Package (PSiP) is featured to be the smallest mounting area in the industry by integrating all necessary components (including an inductor) for a DC-DC converter (so-called DC to DC switching regulator). When used in communication infrastructure and industrial devices, this integrated power module offers improved performance in heat dissipation and noise profile. Overall, PSiP simplifies the power system design, reduces heat and noise emission from the circuit board, and eventually shortens the overall design process.
