MT3540 - 1.2MHz Step-Up Converter
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 extend
