产品概述 返回TOP
The CXSU63205 is a constant frequency, 6-pin SOT23 current mode step-up converter
intended for small,low power applications. The CXSU63205 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 CXSU63205 features automatic
shifting to pulse frequency modulation mode at light loads. The CXSU63205 includes
under-voltage lockout, current limiting, and thermal overload protection to prevent
damage in the event of an output overload. The CXSU63205 is available in a small 6-pin
SOT-23-6 package.
