Quasi-resonant Switching Power Supply
|LTspice Version(Coming Soon)
Switching Power Supply with low EMI and high power
efficiency can be achieved more easily by applying
Quasi-Resonant techniques. The power supply is well
suited for printers and LCD TVs applications that are
noise sensitive. Fuji Electric has developed FA5541
Quasi-Resonant controller IC that is energy-saving
and possible to drive a power MOSFET directly.
Quasi-Resonant Switching Power Supply Design Kit is
a ready-to-use SPICE simulation project that enable
designers to simulate FA5541 power supply application
circuit. The designer can edit their design and verify
the operating characteristics of the power supply by:
This will help the designers find the design flaws
before the production cycle. The circuit can be effectively
tested without the possibility of destroying their parts.
And simulations with the Design Kit is much more quickly
than to build and evaluate the real circuit.
FA5541 characteristics and functions are modeled one
by one compared to the datasheet. The models in the
Design Kit have been evaluated and compared with
measurement data to verify their accuracy.
Quasi-Resonant Switching Power Supply Design Kit
•set of folders that contain OrCAD PSpice project files
•models of the devices using in the design that include
library file, schematic symbol, and evaluation report to
show the model accuracy.
Please check out documents below for the detail and
example of using the Design Kit.
