The XB61040 is a low-power, high-frequency DC-DC step-up (boost) converter from Xinluda, supplied in a SOT-23-5 package. It is used to drive white LED backlights and generate LCD bias voltages in portable, battery-powered devices.

What package does the XB61040 come in?

The XB61040 is available in a compact 5-pin SOT-23-5 surface-mount package, suitable for space-constrained portable designs.

What are the input and output voltage ranges of the XB61040?

The XB61040 operates from a 1.8 V to 6 V input and can boost to an adjustable output of up to 28 V, with a 400 mA internal switch and switching frequency up to 1 MHz.

What is the difference between the XB61040 and XB61041?

Both are high-frequency boost converters in SOT-23-5 with the same 1.8-6 V input and up to 28 V output. The XB61040 has a 400 mA internal switch current, while the XB61041 has a 250 mA internal switch current.

Why is the XB61040 hard to find?

The XB61040 is a Request-For-Quote part with little to no authorized-distributor availability. Pacific Component Xchange specializes in sourcing scarce and hard-to-find power-management ICs like this one.
