Understanding SMPS Dynamic Load Response and How to Fix It
Switch Mode Power Supplies (SMPS) are popular in DIY electronics, but they often face dynamic load response issues. When the load on the SMPS changes suddenly, voltage spikes or drops can occur, potentially damaging sensitive components or causing erratic behavior in circuits. The Problem : When devices like motors, relays, or LEDs switch …

SMPS Voltage Feedback Design: A Beginner’s Guide
The Problem : Switch Mode Power Supplies (SMPS) are widely used in electronics projects, but maintaining stable output voltage can be tricky. The feedback loop is critical—it regulates voltage by comparing the output to a reference and adjusting accordingly. If not designed properly, it can lead to voltage fluctuations, inefficiency, or even circuit failure. …
Understanding MOSFET Thermal Impedance: A Beginner’s Guide
The Problem : When using MOSFETs in circuits that handle high power, heat dissipation becomes a critical concern. Thermal impedance determines how efficiently heat moves from the MOSFET’s junction (internal core) to the surrounding environment. If the thermal impedance is too high, the heat stays trapped, leading to overheating, reduced efficiency, and possible damage. …

MOSFET Pulse-Width Modulation Guide for Electronics Enthusiasts
If you’re diving into electronics projects, you’ve probably encountered Pulse-Width Modulation (PWM), especially when controlling motors or LEDs. The concept of PWM can seem complex, but in simple terms, it’s just a way of controlling the power supplied to a device by switching it on and off rapidly. The more on-time (duty cycle) the device …

Reverse Protection in Telecom Systems: A Beginner’s Guide
The Problem : When designing telecom systems, one common issue that can damage your circuit or device is reverse polarity. This happens when the power supply is connected with the wrong polarity—positive to negative and negative to positive. This can damage sensitive components like microcontrollers, MOSFETs, and ICs, causing the system to fail. …

SMPS PCB Layout Guidelines for Beginners
Switch-Mode Power Supply (SMPS) designs are essential in modern electronics, but improper PCB layout can lead to inefficiency, heat buildup, or noise issues. A key challenge many engineers face when working with SMPS is the placement of components on the PCB. Improper routing can cause voltage drops, reduce efficiency, or even damage sensitive parts. Fortunately, …
MOSFET Short-Circuit Protection Circuits: Essential for Safe Prototyping
In electronics, MOSFETs (Metal-Oxide-Semiconductor Field-Effect Transistors) are widely used in switches and amplifiers. However, they are sensitive to short circuits, which can cause damage or failure. When a short circuit occurs, excessive current flows through the MOSFET, potentially burning out the component. To fix this issue, adding a short-circuit protection circuit can help. A simple …
