Key Features
- 350mA output current with 6MHz switching frequency enabling ultra-compact inductor and capacitor selection
- Fixed 1.8V regulated output ideal for powering microcontrollers, DSPs, and low-voltage logic ICs
- Input voltage range from 2.3V to 5.5V supporting single-cell Li-Ion, USB, and 3.3V/5V supply rails
- 6-ball XBGA wafer-level package for minimal board space in wearables and IoT modules
Applications
The TPS62619YFDT is designed for space-constrained portable applications such as wearable electronics, IoT sensor nodes, and wireless communication modules where a compact 1.8V power rail is required. Its 6MHz switching frequency dramatically reduces the size of external passive components, enabling sub-millimeter inductor selection and small-value capacitors. The wide 2.3V to 5.5V input range makes it compatible with Li-Ion battery packs, USB power, and 3.3V regulated supplies.
