Charge Pump Power-On: A Silent Revolution for Compact Voltage Solutions

Charge pump technology is increasingly popular in the field of DC/DC voltage regulation due to its compact size, high efficiency and cost-effectiveness, especially in applications such as TFT-LCD backlighting and gate driving circuits. Charge pumps use capacitors instead of inductors to double input voltage with minimal components, reduce electromagnetic interference, and provide negative voltages for sensors and RF amplifiers. Inductive converters dominate high-power applications, while charge pumps perform well in low-power, space-constrained designs, and are expected to be increasingly used in portable and cost-sensitive electronics.
