Switched Capacitor Voltage Converter

Switched Capacitor Voltage Converter

A switched capacitor voltage converter performs energy transfer and voltage conversion using capacitors. There are mainly two types of switched capacitor voltage converters, first is the voltage inverter circuit and the second is the voltage doubler circuit. These types of circuits are commonly known as charge pump circuits. In this project, we will design a switched capacitor voltage inverter using Texas Instruments LMC7660S IC, and […]

High Power High Efficiency Buck Converter Circuit using TL494

High Power High Efficiency Buck Converter Circuit using TL494

A buck converter (step-down converter) is a DC-to-DC switching converter that steps down voltage while maintaining a constant power balance. The main feature of a buck converter is efficiency, which means with a buck converter on board, we can expect extended battery life, reduced heat, smaller size, and improved efficiency. We previously made a few simple Buck converter

TEENY TINY BLUETOOTH TRANSMITTER RUNS ON LESS THAN 1 MW

TEENY-TINY BLUETOOTH TRANSMITTER RUNS ON LESS THAN 1 MW

You’re probably swimming in Bluetooth radio signals right now. But none of those are coming from the smallest, lowest-power end of the Internet of Things. These battery-powered and energy-harvesting millimeter-scale sensors are meant to last for years without needing replacement, but their radios can’t muster the energy needed to communicate using even the lowest energy
