Fixed Isolated Modules

Würth Elektronik Fixed Isolated Modules offer fixed input voltages of 3.3V/5V/12V/24V and a fixed 5V output voltage. These devices are suitable for applications in interface isolation/communication (RS232, RS485, CAN) to eliminate ground loops. The MagI3C modules operate at a typical 24V to 5V conversion at 0.2A, achieving 80% efficiency for SIP-4 and 81% for SIP-7. The FISM series offers fixed output voltage, fully integrated DC/DC power supplies. These devices require no external components for operation, which reduces design effort and keeps complexity to a minimum. The Würth MagI3C modules integrate the switching power stage, inductor, input, and output capacitors in one package. These modules comply with the low-noise electromagnetic emission norm EN 55022 class B. Approvals include IEC/EN60950-1, 2nd Edition; UL60950-1, 2nd Edition; and CSA C22.2 No. 60950-1-07, 2nd Edition.
