PL2628 是DC-DC 升压转换器，SOT23-6 封装。第六脚是不连接丝印打字：B628
The PL2628 is a constant frequency, 6-pin SOT23 current mode step-up converter intended for small, low power applications. The PL2628 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 PL2628 features automatic shifting to pulse frequency modulation mode at light loads. The PL2628 includes under-voltage lockout, current limiting, and thermal overload protection to prevent damage in the event of an output overload. The

PL2628 is available in a small 6-pin SOT-23 package.
