PSiP (Power Supply in Package)

Product Overview

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 shorten the overall design process.

Features

Feature 1 High Efficiency

  • PSiP consists of a MOSFET with LOW on-resistance. With the implementation of Skip-mode function, this power module is able to achieve high efficiency at light load condition.
    Under Continuous-Mode (FCCM) operation, the efficiency can reach a maximum of 95%.

Feature 4 Low Heat Generation

  • PSiP achieves low heat generation by introducing new advanced packaging structure and design technology.

(1) Evolution of PKG structure : Reduce area of heat generated by high integrated PKG technology.

DC-DC Module with built-in Inductor PSiP Low Heat Generation Performance

Allows heatsink to be downsized or removed.


(2) Evolution of Design technology : Reduce heat generated by increasing the efficiency (Loss reduction).

Efficiency (Vin=12V, Vout=3.3V @9A)
MCP DCDC 89.1%
PSiP 91.5%

Feature 5 Low Noise

  • Low noise suitable for integration of power supplies

DC-DC Module with built-in Inductor PSiP Low Noise

Simplifies anti-noise measures.


Integrating high-current wires and the wires that cause noise into a single package reduces the layout design cost and risk of power supplies.

DC-DC Module with built-in Inductor PSiP Short Design Time

Increases the development efficiency.
