When Grounds are Separated
Frederik Dostal Field Applications Engineer Analog Devices, Inc.

How should you proceed with a switching regulator with an analog ground (AGND) and a power ground (PGND)? This is a question asked by many developers designing a switching power supply. Some developers are accustomed to dealing with a digital GND and an analog GND; however, their experience frequently fails th

Are you SiC of Silicon? - Part 1
By: Anup Bhalla, Vice President Engineering, UnitedSiC

SiC applications began in the 2000s with the adoption of SiC JBS diodes into PFC applications. This was followed by the use of SiC diodes and FETs in the PV industry. But the recent surge in applications relating to EV On-board chargers and DC-DC converters is driving SiC growth. The nascent adoption in the EV

Two Steps to High Voltages
Frederik Dostal

If a high voltage needs to be generated from a low voltage, a boost converter can be used. This represents one of the three elementary switching regulator topologies and requires only two switches, an inductor, and input and output capacitors. Besides the boost converter, the other basic topologies are the buck co
