Description

  • LM34904EVM, Evaluation Module helps designers evaluate the performance of the LM34904 current limited power switch. The LM34904 is a 0.5A PFET switch used to control the input voltage of electronic devices. It is easily integrated into system designs that have a 2.8V to 5.3V voltage rail. Besides the 0.4U PFET switch, the LM34904 can be enabled or disabled by a logic signal. The IC monitors the presence of a down-stream electronic device via a dedicated pin to decide whether to turn on the PFET switch. A power good signal generated by the IC can be used by system control to determine the status of the switch

Key Features

  • Conversion Type
    DC to DC
