In voltage doubler applications, LTC7820 can start-up without capacitor inrush charging current if the input voltage is ramping up slowly from zero. As long as the input voltage ramps up slow (in ...

Also note that the output voltage here is not actually doubled even though the circuit appears to be identical to the doubler circuit. This circuit was hay wired to prove that it functions as expected ...

The output voltage is roughly the input voltage times the number of capacitor/diode pairs; for example, a voltage doubler uses two capacitor/diode pairs. A voltage tripler uses three pairs.

The capacitor/diode pairs rectify the voltage, with the capacitors discharging in parallel series to double the output voltage. But how does the variable load (RL) affect the output?

This multiplier consists of capacitors and diodes that take the flyback’s alternating output and smooth it out to flat DC but while multiplying the voltage over some number of stages.

General-purpose analog-multiplier ICs often incorporate attenuators or even amplifiers at both input and output. This permits scaling of the signal to within the voltage limits for a given circuit.

> Other 1.8 to 3.6V output, 0.9V to 1.8V input voltage doubler STAR4003 is designed in a TSMC 40nm process with 3.3V tolerant devices. It outputs an open loop doubled voltage from the input supply.

U1, a switched-capacitor voltage doubler, accepts the -5-V input and produces a +5-V output. A regulated voltage inverter (U2) then accepts the +5 V and produces a -3-V output.

For the gate drivers of high-power IGBTs, mosfets, SiC mosfets and GaN hemts, Infineon has introduced an isolated power supply IC that can generate asymmetric output voltage rails. Each member of the ...
