... The LTC3250-1.5/LTC3250-1.2 will remain in the low current operating state until the output has dropped enough to require another burst of current. Unlike traditional charge pumps whose burst current is dependant on many factors (i.e. supply voltage, switch resistance, capacitor selection, etc.), the LTC3250- 1.5/LTC3250-1.2’ ...
