The step-up DC/DC converter is based on the MC34063 chip control. It can be used with a low input voltage of 3.5 V, a voltage of 9 V, and a current of 150 mA. When the ideal application is running at 9 v, a lithium ion or USB interface is required to provide power. 3.5V to 9V boost circuit converter physical screenshot: Screenshot of the boost DC/DC converter circuit: The boost DC/DC converter parameters are as follows: details as follows: Input voltage range: 3.5V - 8VOutput voltage 9V with currrent capacity 150mA100mVpk ripple @150mA output currentBest for 3.7V Battery or USB powered devices A solar lamp, also known as a solar light or solar lantern, is a lighting system composed of a LED lamp, solar panels, battery, charge Controller.The usage of the LED BULB is very wide.Like light in home,in street,etc. Solar Street Light,Solar Garden Lights,Outdoor Solar Lights,Solar Lanterns NANTONG RONGCHANG IMPORT&EXPORT CO.,LTD , https://www.ergsolarcn.com
