Choose the right step-up/down voltage regulator for portable applications


https://www.electronics-lab.com/choose-the-right-step-updown-voltage-regulator-for-portable-applications/

Reno Rossetti & Inyong Kim discuss about the power needs on portable devices and help us choose the right regulator. A popular power source for portable devices is a single lithium-ion cell with 4.2V at full charge and 2.8V at end of discharge. However, some functions within portable electronics, such as a SIM card and […]
