TX9715
The TX9715 is a constant frequency, current mode step-up converter intended for small, low power applications. The TX9715 switches at 800KHz 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 TX9715 includes under-voltage lockout, current limiting, and thermal overload protection to prevent damage in the event of an output overload. The TX9715 is available in a small SOT23-6 package.
