The Charge Pump DC-to-DC Converter (part number 61K3539) is designed to convert an input voltage range of +1.5V to +10V to a corresponding negative output voltage of -1.5V to -10V. It operates with high efficiency, achieving typical voltage conversion efficiency of 99.9% and power efficiency of 98%. The device requires only two external capacitors for operation, simplifying the design and reducing costs compared to inductor-based solutions. This converter is available in an 8-pin Small Outline (SOIC) package and is suitable for applications such as RS-232 negative power supplies, voltage multiplication, and providing negative supplies for data acquisition systems. It features improved ESD protection of 3 kV and operates with a low power consumption of 80 µA at a 5V input. The on-board oscillator operates at a nominal frequency of 10 kHz, with the option to lower the frequency for reduced supply current by using an external capacitor. The device is also available in various temperature ranges, making it versatile for different operating conditions.
