SMPS Output Noise Reduction Tips – Clean Power for Your Projects!
The Problem : Switch Mode Power Supplies (SMPS) are efficient, but they often generate output noise—tiny voltage ripples that can interfere with sensitive analog circuits, sensors, or audio systems. This high-frequency noise can cause unpredictable behavior in microcontrollers or signal drift in ADCs.
The Solution : To reduce output noise, …

SMPS High-Efficiency Design Tips
The Problem : An SMPS that wastes power as heat shortens battery life and needs larger heatsinks. Inefficiency usually comes from high switching losses (slow MOSFETs) and conduction losses (high-R<sub>DS(on)</sub> parts, lossy capacitors).
The Solution : Choose low-gate-charge MOSFETs so they turn on/off faster. Use low-ESR output capacitors to slash …
SMPS Low-Ripple Component Selection – A Quick Guide
The Problem : When designing or building an SMPS (Switch Mode Power Supply), high output ripple can cause instability in sensitive electronics like microcontrollers, audio amplifiers, or sensors. Ripple is essentially unwanted AC noise on your DC output, and it’s often caused by poor component choices—especially capacitors and inductors.
The Solution …

SMPS Load Transient Tuning Made Simple
The Problem: SMPS Struggles with Sudden Load Changes Switch Mode Power Supplies (SMPS) are great for efficiency—but when your circuit demands a sudden increase or drop in current (called a load transient), the SMPS can momentarily dip or spike in voltage. This can cause glitches in microcontrollers or reboots in sensitive devices. …

Low Voltage Smart Plug Power Supply Tips
The Problem: Powering Smart Plugs Safely at Low Voltage Smart plugs need compact, low voltage power supplies to operate safely from 230V AC. Without proper design, they can overheat, fail, or drain excess power—not ideal for small, energy-efficient devices.
The Solution: Use a Capacitive Dropper or Compact SMPS For low-power …
SMPS Output Filtering Tips for Clean Power
Switch-mode power supplies (SMPS) are highly efficient, but they often produce unwanted noise or ripple at the output. This can interfere with sensitive components in your projects. The good news is that output filtering can reduce these disturbances and give you clean, stable power. The Problem : When an SMPS operates, it …
Powering Low Voltage Smart Lights the Right Way
Smart lighting is a favorite among electronics hobbyists and prototypers across India. But when using low voltage (5V or 12V) systems, power reliability becomes a common challenge—flickering LEDs or resets when brightness spikes usually signal an inadequate power source. The Problem : Low voltage smart lights like RGB strips or Wi-Fi-enabled bulbs …
Reliable Power for Low Voltage Smart Lights – A Simple Guide
Smart lights are getting popular in Indian homes and DIY projects. But one common issue is power instability in low voltage setups (typically 5V or 12V). Flickering or total shutdowns often happen due to undervoltage or poor current handling. The Problem : Low voltage smart lights (like Wi-Fi/Bluetooth-controlled LEDs) often draw spikes …
