Overview

The HT1541 is a current mode step up converter intended for small, low power applications. The HT1541 switches at 1.3MHz 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 HT1541 operates from an input voltage as low as 2.5V and can generate 12V at up to 300mA from a 5V supply. The HT1541 includes under-voltage lockout, current limiting, and thermal overload protection to prevent damage in the event of an output overload. The HT1541 is available in a small 5-pin TSOT23 package or QFN-8 (2mmX2mm) package.
