PRODUCTION DATA.
Refer to the PDF data sheet for device specific package drawings
The default output voltage and enabling of the regulator during startup sequence is defined by OTP bits.
After start-up the software can change the output voltage with the RANGE and VSEL bits in the SMPSx_VOLTAGE register. The value 0x0 disables the SMPS (OFF).
The operating mode of an SMPSx when the TPS65903x-Q1 device is in ACTIVE mode can be selected in SMPSx_CTRL register with MODE_ACTIVE[1:0].
The operating mode of an SMPSx when the TPS65903x-Q1 device is in SLEEP mode is controlled by MODE_SLEEP[1:0] bit depending on SMPS assignment to NSLEEP and ENABLE1, see Table 6-13.
Soft-start slew rate is fixed (Tramp).
The pulldown discharge resistance for OFF mode is enabled and disabled in the SMPS_PD_CTRL register. By default, discharge is enabled.
SMPS behavior for warm reset (reload default values or keep current values) is defined by the SMPSx_CTRL.WR_S bit.
