SL15762.5A High Efficlency 1.2MHz Step-Up Converter

GENERAL DESCRIPTION ：        

 FEATURES The  SL1576   is a constant  frequency, 6-pin SOT23 current mode step-up converter intended for small,  low power  applications. The SL1576  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 SL1576  features automatic shifting to pulse frequency modulation mode at  light  loads. The SL1576  includes under-voltage lockout, current limiting, and thermal overload protection to prevent damage in the event of an output overload. The SL1576   is available  in a small 6-pin SOT-23 package.
