ZHCSK81A September 2019 – October 2020 TPS65296
PRODUCTION DATA
There are specific sequencing requirements for the LPDDR4/LPDDR4X VDD1 and VDD2 rails. The TPS65296 follows the power rail sequence requirements as shown in Figure 7-1 and Figure 7-2. VDD1 is greater than VDD2 at all times during ramp up, operating, and ramp down. The VDDQ output ramp and stable within 35 μs after VDDQ_EN asserted.
