Figure 1: Reference schematic of a buck converter Vin = 24 V; Vout = 5 V

Annika Frankemölle, Alexander Lang / Editor: Gerhard Stelzer, Würth Elektronik

Increasing current densities and short switching times in MOSFETs are placing ever greater stress on the dielectric strength of inductors. Molded inductors with a distributed air gap based on iron powder enable high inductance values in the smallest of spaces and thus increase the power density. A new test con

Convert a buck regulator into a high-current LED driver

Jon Kraft, Applications Engineer, Analog Devices

LEDs promise to change the world, and few doubt that they will. However, a key limiter to more rapid adoption is the cost of the LEDs themselves. The cost breakdown of LED luminaires varies, but it

Isolated uModule Power Converter

Willie Chan Sr. Product Marketing Engineer Linear Technology

Properly implemented, galvanic isolation is an effective defense against disturbances in the ground plane often referred to as ground loops, which occur as a result of varying electrical potentials. Physical limitations require that electrical components on a PCB connect to the ground plane at different physical
