Charge pumps (inductorless) are not a specific brand but a category of electronic components used for voltage conversion without inductors. They are widely utilized in industries such as consumer electronics, automotive, and industrial automation for power management. Leading manufacturers of charge pumps include Texas Instruments (USA), Analog Devices (USA), and Maxim Integrated (USA, now part of Analog Devices). These companies provide high-efficiency, compact charge pump solutions for applications like LED drivers, battery-powered devices, and voltage inverters. Products typically feature low noise, small footprints, and are ideal for space-constrained designs.
