Low Voltage Smart Doorbell Power Guide – Stay Safe & Efficient

⚠️ The Problem :   Smart doorbells with video, Wi-Fi, or BLE modules need steady low-voltage power (3.3V–5V), but many installations still use 12V or 230V AC from traditional doorbells. Directly connecting modern circuits to these sources risks overheating, instability, or even damage.   🛠️ The Solution :   To safely power your smart doorbell …

MOSFET High-Current Load Design – Made Easy!

⚠️ The Problem :    When switching high-current loads like motors or heating elements, MOSFETs are a great choice—but only if designed right! If you use the wrong type or don’t consider R<sub>DS(ON)</sub> (the drain-source resistance), the MOSFET will overheat and waste power.   🛠️ The Solution :    For high-current switching, use low R<sub>DS(ON)</sub> …

SMPS Efficiency at Light Loads – Boost It the Right Way!

🔍 The Problem :   Many SMPS units are designed for medium-to-high loads. But when the load drops—like during standby or in low-power IoT devices—they often become inefficient. This inefficiency is due to fixed switching losses and idle power consumption, even when your circuit draws just a few milliamps.   🛠️ The Solution :   …
