TYPICAL CURCUIT DIAGRAM

DESCRIPTION

The FDSM series of the MagI

C power module family is

a ﬁxed output voltage, fully integrated dc/dc power sup-

ply. The module integrates the switching power stage,

control circuitry and inductor all in one package.

The module requires no external components for ope-

ration. Input and output capacitors are integrated. De-

sign effort and complexity is reduced to a minimum.

The FDSM ensures fast time to market and low deve-

lopment costs.

It is pin compatible with the common 78xx linear re-

gulator series. The high efﬁciency reduces the power

dissipation and in many cases heatsinks and assembly

parts are no longer necessary.

Typical 12V to 3.3V conversion achieves 85% efﬁcien-

cy. 12V to 5V conversion achieves 92 %.

The standard THT package allows for easy assembly.

TYPICAL APPLICATIONS

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

• Replacement for linear regulators

• Interface and microcontroller supply

• General purpose

FEATURES

• Peak efficiency up to 95%

range

• Thermal shutdown

• Integrated capacitors and inductor

• Pulse skipping for high efﬁciency at light loads

• Fixed 570 kHz switching frequency

• Output overvoltage protection

• RoHS & REACH compliant

• UL94V-0 package material

WPMDL9500xx / 17395xx78 MagI3C Power Module FDSM - Fixed Step Down Regulator Module PROTECTIVE FEATURES Overvoltage transient protection This protection mode minimizes the occurance of output voltage overshooting. Once the output voltage reaches an overvoltage threshold the switching from Vin will be stopped immediately via the high side FET. When the output voltage falls below the overvoltage trip the high side FET will be enabled again.
