BELLING BL8042B
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. The BL8042B includes under-voltage lockout, current limiting, and thermal overload protection to prevent damage in the event of an output overload.| Part No. | BL8042B |
