54 / 104 page  3.54 INTEGRATED SUPPLIES – ENABLE CONTROL, DVM CONTROL 3.54.1 DVM AND NON-DVM SUPPLIES 3.54.2 DVM AND NON-DVM SUPPLY ENABLE TPS658620 Advanced Power Management Unit SLVS993 – OCTOBER 2009 www.ti.com The TPS658620 has two types of voltage control for the integrated supplies: 1. DVM supplies: SM0, SM1, LDO2 and LDO4 are DVM supplies with dedicated register sets that enable a controlled transition from an initial voltage to a final voltage. The initial voltage, final voltage, and voltage transition start time are set via I2C. SM0 and SM1 have I2C programmable slew rate. 2. NON-DVM supplies: LDO0, LDO1, LDO3, LDO5, LDO6, LDO7, LDO8, LDO9, SM2 and RTC_OUT outputs can be changed, but without slew rate and transition start time control. The output of these supplies will be changed to the new value as soon as TPS658620 sends the ACK of the I2C command setting the new output voltage. All the integrated supplies can be turned on/off by RAM enable bits. All the supplies (with exception of LDO5, LDO9 and RTC_OUT LDO's) have two enable bits on distinct registers (registers 0x10, 0x11, 0x12, 0x13, 0x14). A supply will be enabled when ANY of its enable bits, in the registers below, are set to 1. Each supply will be disabled when ALL of the enable bits for that supply are set to 0. For example: SM0 enabled: SM0_ENA=1 OR SM0_ENB=1, SM0 disabled: SM0_ENA=0 AND SM0_ENB=0 Table 3-18.
