The TPS61040M5/TR with SOT-23-5 DC-DC Converter manufactured by HGSEMI is a charge pump converter designed for providing a regulated output voltage from an input voltage source that can range from 1.4V–5V. It features high efficiency and low noise, and is designed for applications with limiting board space requirements. This device features a special constant frequency architec—ture, and works in either a 1x or 2x mode, which provides for a combination of fast transient response, low ripple noise and wide input and output voltage range. The TPS61040M5/TR is RoHS compliant, and is ideal for space-constrained applications.
