一,产品概述(General Description)      

      The CXSU6340 is a step-up converter that provides a boosted output voltage Z0r嘉泰姆

from a low voltage source. Because of its proprietary design, it starts up at Z0r嘉泰姆

a very low input voltage down to 0.9V, and only consumes 15uA at standby, makingZ0r嘉泰姆

it an ideal choice for single cell alkaline/NiMH battery operations.A switchingZ0r嘉泰姆

frequency of 1MHz minimizes solution footprint by allowing the use of tiny, lowZ0r嘉泰姆

profile inductors and ceramic capacitors. The current mode PWM design is internallyZ0r嘉泰姆

compensated, reducing external parts count.Z0r嘉泰姆

  CXSU6340 is available in SOT23-5 Package.Z0r嘉泰姆
