GENERAL DESCRIPTION
The TP3605 is a constant frequency, 6-pin SOT23 current mode step-up converter intended for small, low power applications. The TP3605 switches at 1MHz 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 TP3605 features automatic shifting to pulse frequency modulation mode at light loads. The TP3605 includes under-voltage lockout, current limiting, and thermal overload protection to prevent damage in the event of an output overload. The TP3605 is available in a small 6-pin SOT-23 package.
