What is the primary function within the end product?
Operating from AC or DC?
What topology would you like to use in your design?
Forward: Forward converters are isolated buck derived converters that are popular in high power applications (>75 W) and are typically found in telecommunications products and ATX power supplies. They provide a cost effective solution and fill the gap between flyback converters and high power bridge converters.
Flyback: Flyback converters are isolated buck-boost derived converters that are popular among low power applications(<250 W) and are found in a vast majority of consumer products (notebook adapters, DVD players, set-top boxes, satellite receivers, LCD monitors). These converters are simple to design and use and are a cost effective solution for power conversion requirements.
Resonant: Resonant converters are isolated soft-switching converters that are popular in high power applications (>75 W) and are typically found in Flat Panel display power converters, high power AC/DC notebook adapters, industrial and medical power sources, and offline battery chargers. They are highly efficient due to reduced switching losses (zero-voltage switching and zero-current switching) and have much higher switching frequencies than comparable PWM controllers.
How many output channels are needed?
Does the output of your power supply need to be electrically isolated from the input?
Isolation is the electrical separation between the input and the output of a circuit or device. Power converters that have common grounds are not isolated. The measure of isolation is resistance and/or capacitance between the input and output.
How many conversion stages?
What level of integration does the design require?
