DETAILED DESCRIPTION
POWER REFERENCE
The bandgap voltage reference is filtered by using an external capacitor connected across the VREF output and
the analog ground REFGND (see RECOMMENDED OPERATING CONDITIONS, Recommended Operating
Conditions). The VREF voltage is distributed and buffered inside the device.
POWER SOURCES
The power resources provided by the TPS65910 device include inductor-based switched mode power supplies
(SMPS) and linear low drop-out voltage regulators (LDOs). These supply resources provide the required power
to the external processor cores and external components, and to modules embedded in the TPS65910 device.
Two of these SMPS have DVS capability SmartReflex Class 3 compatible. These SMPS provide independent
core voltage domains to the host processor. The remaining SMPS provides supply voltage for the host processor
I/Os.
Table 12 lists the power sources provided by the TPS65910 device.

EMBEDED POWER CONTROLLER
The embedded power controller manages the state of the device and controls the power-up sequence.
STATE-MACHINE
The EPC supports the following states:
No supply: The main battery supply voltage is not high enough to power the VRTC regulator. A global reset is
asserted in this case. Everything on the device is off.
Backup: The main battery supply voltage is high enough to enable the VRTC domain but not enough to switch
on all the resources. In this state, the VRTC regulator is in backup mode and only the 32-K oscillator and RTC
module are operating (if enabled). All other resources are off or under reset.
Off: The main battery supply voltage is high enough to start the power-up sequence but device power on is not
enabled. All power supplies are in OFF state except VRTC.
Active: Device power-on enable conditions are met and regulated power supplies are on or can be enabled with
full current capability.
Sleep: Device SLEEP enable conditions are met and some selected regulated power supplies are in low-power
mode.
