BL8042B Overview
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.
