SWITCH NODE LAYOUT CONSIDERATIONS FOR EMCARTICLEThe switch node of a switching regulator or power converter circuit is a critical conduction path that requires special attention when designing the PCB layout. This circuit node is where one or more power semiconductor switches (such as a MOSFET or diode) connect to a magnetic energy-storing device (such as an inductor or transformer winding). The switching signals of this circuit node contain fa...

QUICK TIPS TO DIAGNOSE AND STABILIZE AN UNSTABLE SWITCHING POWER SUPPLYARTICLEAn unstable power supply can cause severe system issues, such as audible noise from the passive components, unexpected jittering in the switching frequency, extreme oscillations on the output voltage during load transient events, and failures in the semiconductor switches. While there are various reasons for instability, an un-tuned compensation network accounts for majority of instability issues ...

USING EXTERNAL KNOBS TO IMPROVE TRANSIENT PERFORMANCE OF BUCK REGULATORS WITH AN INTEGRATED COMPENSATION NETWORKARTICLEThe high power density requirement and board-level space constraints in modern applications — such as lighting, ADAS, and USB — call for higher integration in buck regulators. There is a trend to integrate MOSFETs and compensation networks inside the chip. This integration of the compensation network’s passive components saves cost, board space, and design iterations. However, it...

ANALOG SIGNAL VS. DIGITAL SIGNALSARTICLEA signal is an electromagnetic or electrical current that carries data from one system or network to another. In electronics, a signal is often a time-varying voltage that is also an electromagnetic wave carrying information, though it can take on other forms, such as current. There are two main types of signals used in electronics: analog and digital signals. This article discusses the correspond...
