DC to DC Chip SOT23-5 MP1540DJ-LF-Z 1.3MHz, 18V Step-Up Converter Power Management ICs
Description
The MP1540 is a 5-pin thin TSOT23 current mode step-up converter intended for small, low power applications. The MP1540 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 MP1540 operates from an input voltage as low as 2.5V and can generate 12V at up to 200mA from a 5V supply. The MP1540 includes under voltage lockout, current limiting, and thermal overload protection to prevent damage in the event of an output overload. The MP1540 is available in a small 5-pin TSOT23 package.
