一,产品概述(General Description)      eau嘉泰姆
直线eau嘉泰姆
     The CXSU6339 is a step-up converter that provides a boosted outputeau嘉泰姆

 voltage from a low voltage source. Because of its proprietary design, it startseau嘉泰姆

 up at a very low input voltage down to 0.9V, and only consumes 15uA at standby, eau嘉泰姆

making it an ideal choice for single cell alkaline/NiMH battery operations.A eau嘉泰姆

switching frequency of 1MHz minimizes solution footprint by allowing the use eau嘉泰姆

of tiny, low profile  inductors and ceramic capacitors. The current mode PWM eau嘉泰姆

design is internally compensated, reducing external parts count.CXSU6339 eau嘉泰姆

is available in SOT23-3 and SOT89-3 Package.eau嘉泰姆
