XB61041 – DC-DC Converter – Xinluda

The XB61041 from Xinluda is a low-power, high-frequency DC-DC step-up (boost) converter in a SOT-23-5 package, boosting 1.8V-6V inputs to outputs up to 28V with a 250mA internal switch current limit. It is a functional equivalent to the TI TPS61041.

The XB61041 is a low-power, high-efficiency DC-DC step-up (boost) converter from Xinluda, supplied in a compact SOT-23-5 package. Designed for small to medium LCD bias supplies and white-LED backlight applications, it steps up low battery voltages from single-cell Li-Ion or dual-cell NiMH/NiCd sources to regulated outputs as high as 28V. The XB61041 is the 250mA switch-current-limit member of the XB6104x family (the XB61040 carries a 400mA limit), and is a functional equivalent to the Texas Instruments TPS61041.

An internal optimized control scheme combined with a low typical quiescent current of 28µA enables high conversion efficiency across the full load-current range. The 250mA switch current limit yields lower output-voltage ripple and allows the use of a smaller-footprint inductor, making the XB61041 well suited to space- and power-constrained portable designs.
