BL8541 Datasheet | Belling

0.9V startup, 1A True Shut-Off Synchronous Boost DC/DC converter DESCRIPTION The BL8541, is a high-efficiency, synchronous stepup switching regulators optimized for batterypowered applications. It supports up to 1A load current and allows the use of small, low cost inductors and MLCC capacitors. The BL8541 starts up as low as 0.9V input voltage and it has true-shutoff function (shut off output to zero voltage when CE pulled low) and real output short-circuit protection. These Features make it ideal for USB interface power supply. Given its high efficiency, the BL8541 device is ideal for small portable applications powered by battery. It consumes as low as 40u A (3V input /3.3V output) at zero load. And its current consumption is less than 1u A in shutdown mode. BL8541 is available in DFN2x2-6 package.
