Introduction

AI Translation

The MT3540 is a constant frequency, 5-pin SOT23 current mode step-up converter intended for small, low power applications. The MT3540 switches at 1.2MHz 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 MT3540 operates from an input voltage as low as 2.5V and can generate 28V at up to 100mA from a 5V supply. The MT3540 features automatic shifting to pulse frequency modulation mode at light loads. The MT3540 includes under-voltage lockout, current limiting, and thermal overload protection to prevent damage in the event of an output overload. The MT3540 is available in a small 5-pin SOT-23 package.
