TPS61253YFFR Synchronous Boost Regulator
TheTPS61253YFFR is a high-efficiency, synchronous boost converter from Texas Instruments, designed to deliver a constant 5V fixed output voltage from a single-cell Lithium-ion or multi-cell alkaline/NiMH battery input. This versatile IC integrates a 0.3-ohm power switch and can deliver up to 5V at 1.2A continuous output current, making it exceptionally suitable for powering portable devices, IoT sensors, and USB-powered peripherals. Housed in a tiny 0.4mm pitch DSBGA package, it achieves an impressive power density, enabling ultra-compact PCB designs. The converter operates with a typical 2.5MHz fixed switching frequency, which allows for the use of very small inductors and capacitors, further minimizing the total solution footprint and cost.
TPS61253YFFR Step-Up Converter Key Features
This converter features a wide input voltage range of 1.8V to 5.5V, seamlessly handling deeply discharged batteries down to 1.8V while maintaining stable output. Its advanced control topology, utilizing an average current mode, achieves high efficiency across a broad load range, with peak efficiency exceeding 95%. Key functionalities include a Power Good indicator for system sequencing, output short-circuit protection, and over-temperature protection, ensuring robust and reliable operation. The chip also offers a low 1µA typical shutdown current, significantly extending battery life in portable applications. It is designed for stable operation with small, low-cost ceramic capacitors and features 100% duty cycle mode for low dropout conditions, preventing premature shutdown.
