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

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

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

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

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

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

compensated, reducing external parts count.zdV嘉泰姆

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