Description
No Connect
Enable. If ENABLE is pulled high or allowed to float high, the chip is powered up. The pin must
be held low for the XRP9710 to be placed into shutdown.
Controller Supply Voltage. Place a decoupling capacitor close to the controller IC. This input is
used in UVLO fault generation.
Analog Ground. This is the small signal ground connection.
Analog Ground. This is the small signal ground connection.
Feedback Pin. Positive input of remote sensing differential amplifier. Connect to the remote
voltage load, positive terminal.
Feedback Pin. Negative input of remote sensing differential amplifier. Connect to the remote
voltage load, negative terminal.
Feedback Pin. Positive input of remote sensing differential amplifier. Connect to the remote
voltage load, positive terminal.
Feedback Pin. Negative input of remote sensing differential amplifier. Connect to the remote
voltage load, negative terminal.
I/O Logic Signal. Can be configured as input or output.
I/O Logic Signal. Can be configured as input or output.
I²C Data. SMBus/I²C serial interface communication.
I²C Clock. SMBus/I²C serial interface communication.
I/O Logic Signal, HV. Open drain, high voltage compliant. Can be configured as input or
output.
Channel Output Power. Output voltage for the internal channel.
Channel Output Power. Output voltage for the internal channel.
Channel Output Ground. Output ground for the internal channel.
Channel Input Power. Internally connected to drain of upper switching MOSFET
Channel Input Power. Internally connected to drain of upper switching MOSFET
Switch Node. Switch node of the internal channel.
Switch Node. Switch node of the internal channel.
Switch Node. Switch node of the internal channel.
