Working with higher voltages, Part 1: Voltage boosters

March 14, 2019 By Bill Schweber Leave a Comment

voltage boosters

Whether for efficiency or due to the device physics, many applications require voltages ranging in the tens, hundreds, or even thousands of volts; the circuits which produce these voltages start with basic charge pumps and extend to voltage multipliers with simple schematics but many subtleties. Lower-voltage circuitry is the trend, with ICs and designs operating […]
