一,产品概述(General Description)      0dJ嘉泰姆
0dJ嘉泰姆
      The CXSU6340 is a step-up converter that provides a boosted output voltage 0dJ嘉泰姆

from a low voltage source. Because of its proprietary design, it starts up at 0dJ嘉泰姆

a very low input voltage down to 0.9V, and only consumes 15uA at standby, making0dJ嘉泰姆

it an ideal choice for single cell alkaline/NiMH battery operations.A switching0dJ嘉泰姆

frequency of 1MHz minimizes solution footprint by allowing the use of tiny, low0dJ嘉泰姆

profile inductors and ceramic capacitors. The current mode PWM design is internally0dJ嘉泰姆

compensated, reducing external parts count.0dJ嘉泰姆

  CXSU6340 is available in SOT23-5 Package.0dJ嘉泰姆
