I. DC-DC Charge Pumps
DC-DC charge pumps are a core product in ON Semiconductor’s range of lightweight power conversion solutions. As inductor-less switching power supplies, they utilise external ceramic capacitors to transfer charge, thereby achieving voltage step-up, step-down and regulation. Requiring no high-power peripheral components such as inductors or power MOSFETs, they offer key advantages including ultra-compact size, low electromagnetic interference and minimal peripheral circuitry, making them the preferred solution for small, low-voltage power supply applications. On Semiconductor’s charge pump products combine adaptive topology technology with intelligent power consumption control, making them ideally suited for battery-powered portable devices.
Key Product Features
Utilising an adaptive fractional-switching topology, these devices maintain high conversion efficiency across a wider input and output voltage range compared to traditional charge pumps. Equipped with resistive modulation loop control technology, they significantly reduce switching noise, making them suitable for precision electronic applications sensitive to electromagnetic interference. They also support automatic switching between constant-frequency and pulse-skipping operating modes, dynamically adjusting power consumption according to load conditions to effectively extend battery life. The entire product range integrates over-voltage, over-current and over-temperature protection functions, ensuring exceptional operational stability.
