The circuit described here is a simple PFC controller using the UCC28180 chip from Texas instruments. The controller operates under average current mode control at a fixed programmable switching frequency of 116 kHz. Simple external current and voltage loop compensation, along with...

With the increase in the demand for 9V PP3 batteries, there is a significant need for an efficient charger. One might be able to find several PP3 batteries that are manufactured majority being NiMH, however, there is an alternative of Li-Ion batteries. This has made it difficult to get...

This SLA Battery charger project is the right choice if you want to obtain maximum battery service life and capacity, along with acceptable recharge time and economy, constant current, constant voltage, and even charge a deeply discharged battery. The project contains all the necessary...

This project helps to optimize the 12V lead-acid (SLA) battery life as it prevents the battery from going into deep discharge. It is very important to disconnect the load before the battery enters into deep discharge as this may destroy or damage the battery cells.  The circuit shown...

The project here is a 48V protected, high side switch designed to switch a 5A output load from input voltages from 8V to 48V. The circuit helps the user to easily ON/OFF the high current and voltage load with over-voltage lockout and over-current protection. The wide input range and low...

TinyCharger is an ATtiny25/45/85-based, single-cell Li-ion battery charger with selectable charging current limit (100mA - 1000mA) and an OLED display for monitoring. For battery charging the TP4056 is used. The TP4056 is a complete constant-current/constant-voltage linear charger for...

If you need safe power to run your project, then this circuit is a possible solution for you. This project provides protection to your system device against over-current, over-voltage, under-voltage, thermal overload, and reverse current flow control to the system device. Basically,...

NGK INSULATORS, LTD., announced that it has commenced collaboration with Renesas Electronics Corporation, on promoting the widespread adoption of maintenance-free IoT devices. As the first phase of collaboration, NGK and Renesas jointly-developed a reference design for a wireless air...
