MT3609L 2.5A, High Efficiency 1.2MHz Current Mode Step-Up Converter

The MT3609L is a constant frequency, 6-pin
SOT23 current mode step-up converter
intended for small, low power applications. The
MT3609L 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 MT3609L features automatic shifting to
pulse frequency modulation mode at light loads. The MT3609L includes under-voltage lockout, current limiting, and thermal overload
protection to prevent damage in the event of an
output overload. The MT3609L is available in a
small 6-pin SOT-23 package.
