Power Stage, Regulator and Inductor in a Robust Package

With the MagI³C VDRM, Würth Elektronik eiSos introduces a new dc-dc voltage converter in the MagI³C power module family in a TO263-7EP package. The input voltage range of the converter covers the range from 6- to 42-Vdc to allow conversion from the 9V, 12V or 24V industry bus.

The product family is expanded with two new modules for 1A and 3A with an adjustable output voltage in the low range of 0.8- to 6-Vdc. The robust modules can be operated at an ambient temperature up to 105°C.

Applications are expected to include: Point-of-Load dc-dc applications from 5V or 3.3V rail; Replacement for linear regulators; Interface and microcontroller supply; DSP and FPGA power supply auxiliary voltages; Portable instruments; and Battery powered equipment.

They are characterized by high efficiency up to 97 percent. The easy-to-solder TO263-7EP package measures 10.16 × 13.77 × 4.57 mm. The entire product family of MagI³C VDRM power modules is available from stock. Free samples can be requested.

Features include:

  • Low conducted and radiated EMI (compliant to EN55022 class B / CISPR-22
  • Very low profile Micro-package
  • Optimized for space constrained applications
  • Small CIN and COUT integrated
  • 3 solder cycles supported
