一,产品概述(General Description)      

      The CXSU6340 is a step-up converter that provides a boosted output voltage pI9嘉泰姆

from a low voltage source. Because of its proprietary design, it starts up at pI9嘉泰姆

a very low input voltage down to 0.9V, and only consumes 15uA at standby, makingpI9嘉泰姆

it an ideal choice for single cell alkaline/NiMH battery operations.A switchingpI9嘉泰姆

frequency of 1MHz minimizes solution footprint by allowing the use of tiny, lowpI9嘉泰姆

profile inductors and ceramic capacitors. The current mode PWM design is internallypI9嘉泰姆

compensated, reducing external parts count.pI9嘉泰姆

  CXSU6340 is available in SOT23-5 Package.pI9嘉泰姆
