The Runic Technology RS6903YF5 is a charge pump DC-DC converter designed to generate a negative output voltage equal to -Vin. It operates from an input voltage of 1.5V to 5.5V and delivers up to 60mA of output current. With a 50kHz switching frequency and a compact SOT-753 package, it is ideal for generating negative supply rails in battery-powered and portable applications.
- Simple Negative Rail Generation: Produces -Vin without inductors, simplifying design and reducing EMI.
- Wide Input Range: Operates from 1.5V to 5.5V, compatible with various battery configurations.
- Compact Package: The SOT-753 package is ideal for space-constrained designs.
- Low Cost: Charge pump topology eliminates the need for inductors, reducing BOM cost.
