In compact, battery-operated, and other low-power applications, charge pump ICs are straightforward and inexpensive options for increasing voltage under mild load situations. Charge pump ICs, unlike boost converters, may function without inductors and other external parts and only need two capacitors for energy storage.
In your design, this saves board space and lowers expenses. In a range of applications, including LED lighting, automotive, industrial, and more, our array of charge pumps comprises components that enable doubled, reversed, or regulated voltage output.
A DC-to-DC converter known as a “EV charge pump” employs capacitors to store energetic charge in order to increase or decrease voltage. Although being electrically simple circuits, charge-pump circuits can achieve remarkable efficiency, sometimes as high as 90 percent.
To manage the connection of a supply voltage across a load through a capacitor, charge pumps require some kind of switching device. A capacitor is connected across the supply in the first stage of a two-stage cycle to charge it to the same voltage.
The circuit is rearranged in the second stage such that the capacitor is connected in series with the supply and the load. By adding the voltages from the original source and the capacitors, this doubles the voltage across the load.
The Global EV charge pump converter market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
The microchip launches TC7660 is a pin-compatible replacement for the TC7660 charge pump converter, which is the industry standard. It uses just two inexpensive capacitors to convert an input range of +1.5V to +10V to an output range of -1.5V to -10V, doing away with inductors and all of the associated costs, size, and EMI.
Operating at a nominal frequency of 10 kHz is the on-board oscillator. It is feasible to operate below 10 kHz for applications requiring reduced supply current by connecting an external capacitor from the OSC to ground. The TC7660 is offered in commercial and extended temperature ranges in both 8-pin DIP and 8-pin SOIC packages.
