一,产品概述(General Description)      mRq嘉泰姆
mRq嘉泰姆
      The CXSU6340 is a step-up converter that provides a boosted output voltage mRq嘉泰姆

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

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

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

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

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

compensated, reducing external parts count.mRq嘉泰姆

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