7 - 42V / 1A / 3.3V 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 89% efficiency.

12V to 5V conversion achieves up to 92% efficiency.

The standard THT package allows for easy assembly.

WPMDH1100xx1S / 173010x42 MagI3C Power Module FDSM – Fixed Step Down Regulator Module LIGHT LOAD OPERATION At light load conditions, the device skips switching cycles in order to keep the output voltage regulated as well as to increase the efficiency under this condition. SOFT-START In order to prevent the output voltage from overshooting during start-up, a soft-start is implemented. The soft-start is internally set and lasts around 1.3ms for both the 173010342 and 173010542.

WPMDH1100xx1S / 173010x42 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 150°C (typ.), causing the device to enter a low power standby state. In this state the MOSFET remains off causing V OUT to fall.
