7 - 28V / 1A / 3.3 or 5V Output

DESCRIPTION

The FDSM series of the MagI

C 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.

TYPICAL APPLICATIONS

• Point-of-Load from 18V, 15V, 12V, 9V rail

WPMDL110xxx1S / 17301xx78 MagI3C Power Module FDSM – Fixed Step Down Regulator Module BLOCK DIAGRAM CIRCUIT DESCRIPTION The MagI³C Power Module 173xxxx78 is based on a non-synchronous step-down regulator with integrated MOSFET, freewheeling diode, power inductor, input and output capacitors. The control scheme is based on a Current Mode (CM) regulation loop.

WPMDL110xxx1S / 17301xx78 MagI3C Power Module FDSM – Fixed Step Down Regulator Module PROTECTIVE FEATURES Over temperature protection (OTP) The junction temperature of the MagI³C Power Module should not be allowed to exceed its maximum ratings. Thermal protection is implemented by an internal Thermal Shutdown circuit which activates at 165°C (typ.), causing the device to enter a low power standby state. In this state the MOSFET remains off causing V OUT to fall.
