Figure 1: Gate driver circuit diagram with a Bourns transformer
While gate driver-based converters deliver improved efficiency, speed and signal integrity, their high frequency switching features can produce elevated levels of conducted electromagnetic interference (EMI), posing challenges to electromagnetic compatibility (EMC) and overall system reliability. To solve this

Figure 1. Electrical schematic of bipolar, bidirectional, 2-terminal power supply: VIN = 5 V to 24 V, VOUT = ±10 V at 3 A
Most electronic systems depend on power voltage rails that are either positive or negative, but a few applications require individual rails that can be both. In these situations, positive or negative power is supplied by the same terminal—that is, the output voltage of the supply can be adjusted through its en

Figure 1: Today’s smart hand tools provide information for machine control and inform the operator of part quality with tolerance indication
In manufacturing, it makes perfect sense to maximize the value of every dollar, but it also means hard choices must be made when selecting handheld gages. For example, myriad issues such as training, warranties, throughput requirements, manufacturing methods and materials, the end-use of the workpiece, and general co

Figure 1: O-Ring Circuit
Among the many benefits of USB Type-C connectors are their small size, easy-to-use features, and versatility. USB Type-C (also called USB-C) can support multiple protocols, such as USB 3.1, DisplayPort, HDMI, and USB PD. The USB Implementers Forum (USB-IF) released guidelines for USB Type-C called USB Type-C Ca
