Introduction A single lithium battery can be increased to 12V 500mA. Does anyone know of a good booster chip. The cheaper EL7516 can step up the voltage from 2.6V to 5.5V to 1.

A single lithium battery can be increased to 12V 500mA. Anyone know what type of booster chip is goo

Using EL7516, 2.6V~5.5V can be increased to 12V, but if the input voltage is low, its boost conversion efficiency will also decrease, because EL7516 increases 12V with voltage d Input greater than 5V and output current is 100mA. The conversion efficiency can reach more than 90% when ~400mA, and the cell voltage of the lithium battery is about 3.2V. Under this input voltage, the 12V output is increased when the current reaches 300mA, the conversion efficiency of EL7516 will be lower. greater than 80%, if the output current reaches 500mA, the efficiency will be even lower, possibly less than 50%, which means that the output current of the lithium battery should be greater than 4A~5A or even higher . Not only the EL7516, but also all DC-DC boost devices are in this situation.
