Switching at 3.5MHz with synchronous rectification, the converter maintains efficiency across load while keeping external inductor and capacitor values small — a practical fit for space-constrained designs like portable instruments or battery-powered IoT nodes. Housed in a 9-bump DSBGA (0.4mm pitch typical), the TPS61259YFFT requires a PCB with fine-trace capability and a stencil designed for wafer-level chip-scale packages. No direct replacement or cross-reference is listed — the part is the current standard offering for this fixed 5.1V boost function.","metaTitle":"TPS61259YFFT Boost Converter – 5.1V Fixed Output","metaDescription":"Texas Instruments TPS61259YFFT step-up boost converter, fixed 5.1V output, 3.9A switch current, 9-DSBGA package.
