The BL8042D is a constant frequency, current mode step-up converter intended for small, low-power applications. The BL8042D 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 BL8042D includes under-voltage lockout, current limiting, thermal shutdown protection and output over voltage protection.
BL8042D is available in SOT23-6 package that is PB-free.
