产品简介The BL8042B is a constant frequency, current mode step-up converter intended for small, low power applications. The BL8042B switches at 1.2MHz and allows the use of tiny, low cost capacitors and inductors 2mm or less in height. Internal soft-start results in small inrush current and extends battery life. The BL8042B includes under-voltage lockout, current limiting, and thermal overload protection to prevent damage in the event of an output overload. BL8042B is available in SOT23-6 package that is PB free.
