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 applica
tions. 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.
