ZHCSI22F October 2017 – December 2021 TPS2662
TI recommends a ceramic bypass capacitor close to the device from IN to GND to alleviate bus transients. The recommended input operating voltage range is 4.5 to 60 V. V(OUT), in the ON condition, is calculated using Equation 4.
GND pin must be connected to the system ground. RTN is the device ground reference for all the internal control blocks. Connect the TPS2662x family support components: R(ILIM), C(dVdT) and resistors for UVLO and OVP with respect to the RTN pin. Internally, the device has reverse input polarity protection block between RTN and the GND terminal. Connecting RTN pin to GND pin disables the reverse polarity protection feature and the TPS2662x gets permanently damaged when operated under this fault event.
