DESCRIPTION

The FDSM series of the MagI3C Power Module family is a

fixed output voltage, fully integrated dc/dc power supply.

The module integrates the switching power stage, control

circuitry, inductor and capacitors all in one package.

The module requires no external components for

operation reducing design effort and complexity to a

minimum.

The FDSM ensures fast time to market and low

development costs.

It is pin compatible with the common 78xx linear regulator

series. The high efficiency reduces the power dissipation

and in many cases a heatsink and assembly parts are

unnecessary.

12V to 3.3V conversion achieves up to 87 efficiency.

12V to 5V conversion achieves up to 91 efficiency.

The standard THT package allows for easy assembly.
