ZHCSGZ0B October 2017 – November 2017 TPS23525
PRODUCTION DATA.
There are several things to keep in mind during layout of the TPS23525 circuit:
● The VEE and SNS pin need to have a Kelvin Sense connection to the sense resistor.
● The VEE trace carries current and needs to be thick and short in order to minimize IR drop and to avoid introducing current sensing error.
● It is recommended to use a net-tie to separate the power plane coming into the RSNS and the Kelvin connection to VEE.
● Connect the Neg48Vx filtering caps, UVEN resistor divider, OV resistor divider, and TMR cap to the "VEE" to insure maximum accuracy.
● The filtering caps on Neg48VB, Neg48VA, and SNS should be placed as close to the IC as possible.
