Here’s a detailed, professional guide on selection and layout of peripheral components for a DC–DC switching power supply, covering design principles, key components, and PCB layout considerations.

let’s break down practical 5 V over-voltage protection (OVP) options and how to size them, centered on three popular approaches: using (1) a voltage-regulator-style series pass element, (2) a BJT (“transistor”) circuit, and (3) a MOSFET.

This is an excellent topic that gets to the heart of modern power electronics. Transformers and inductors are fundamental, yet distinct, components in LED power supplies (also known as LED drivers).

The number of transistors in a microcontroller (MCU) is not a single fixed value — it depends heavily on architecture & features, fabrication technology and target application.

The selection and design of an RS-485 interface is critical for robust industrial, automotive, and building automation systems.

Every MOSFET (except special structures like some RF/LDMOS) is inherently a four-terminal device: gate, source, drain, and body (substrate). In most discrete MOSFETs, the body is tied to the source.

Achieving bidirectional level conversion with the SN74TVC16222A is an excellent use case for this particular chip. Its key feature is the integrated Bus Switch architecture with under-voltage-lockout (UVLO) control, which makes bidirectional level shifting automatic and very straightforward.

Using diodes with microcontrollers is a classic and effective way to manipulate voltage levels, primarily for two purposes: dropping voltage and steering current.
