ZHCSFJ2E September 2015 – October 2024 TPS65094
PRODUCTION DATA
The TPS65094x device provides all the necessary power supplies for the Intel Reference Designs. For an overview of the different OTP configurations, consult Table 4-1. The following VRs are integrated: three step-down controllers (BUCK1, BUCK2, and BUCK6), three step-down converters (BUCK3, BUCK4, and BUCK5), a sink and source LDO (VTT LDO), three low-voltage VIN LDOs (LDOA1–LDOA3), and three load switches that are managed by power-up sequence logic to provide the proper power rails, sequencing, and protection. All VRs have a built-in discharge resistor, and the value can be changed by the DISCHCNT1–DISCHCNT3 and LDOA1_CTRL registers. When enabling a VR, the PMIC automatically disconnects the discharge resistor for that rail without any I2C command. Table 7-1 summarizes the key characteristics of the voltage rails.
