TPS61046YFFT

The TPS61046YFFT from Texas Instruments is a highly integrated boost converter designed for applications requiring high voltage and a compact solution size, such as PMOLED panels and sensor modules. This device integrates a 30-V power switch, an input/output isolation switch, and a power diode, enabling it to output up to 28 V from a Li+ battery or two alkaline batteries.

Key electrical specifications include an input voltage range of 1.8 V to 5.5 V, with a typical switch current of 900 mA. It achieves up to 85% efficiency at a 3.6-V input and 12-V output. The converter features an ultra-low shutdown current of 500 nA and ±2% output voltage accuracy. It also includes power save operation mode at light loads and an internal 10-ms soft start time.

For protection, the TPS61046YFFT incorporates output short circuit protection, output over-voltage protection, and thermal shutdown protection. It operates over a temperature range of -40°C to 150°C.

The TPS61046YFFT is available in a small 0.80-mm x 1.20-mm WCSP package, suitable for surface mounting. This tiny footprint makes it ideal for space-constrained designs.
