TPS65216 – Cost Optimized PMICThe TPS65216 device is a single-chip PMIC designed
to power the AMIC110 and AMIC120 families ofprocessors in lined-powered (5 V) applications. The
TPS65216 device can also power the AM335x familyof processors in always-on applications. The
TPS65216 device provides four DC/DC converters,
one LDO, and integrated power sequencing. By
integrating the power sequencing, users can save costfrom discrete external sequencing components
necessary for the AMIC1x and AM335x family ofprocessors. The TPS65216 device has a streamlined
feature set, making it perfect for systems that only
require a simple power configuration. This PMIC, whenused in conjunction with the AMIC110 processor, areideal for EtherCAT® (Ethernet for Control Automation
Technology) applications. When used with the AM335x

processor, the TPS65216 is suitable for grid
infrastructure applications such as smart meters anddata concentrators. The TPS65216 device integrates
only the minimum required feature set, making it acost-optimized, fully-integrated solution.
TPS650250 – Wide Temperature Range PMICThe TPS650250 device is a single-chip PMIC
designed to power the AM335x family of processors inlined-powered (5 V) applications. The TPS650250
device can power the AM335x family of processors
supporting 300- and 600-MHz frequencies. TheTPS650250 device can also power the AMIC110
processor. The TPS650250 device features three
DC/DC converters, two LDOs, and has a maximum
temperature range up to 125°C. The TPS650250
device has external enable pins for sequencing.
Because the TPS650250 device has a maximum
temperature range up to 125°C, the PMIC is suitable
for automotive applications such telematics, cluster, orindustrial applications which commonly require 105°C
components.

TPS65910 – Most Integrated PMICThe TPS65910x device is an integrated PMIC
designed for applications powered by one Li-ion
battery cell or a 5-V input adapter and can supply
multiple power rails. The TPS65910x device is themost integrated PMIC for the Sitara™ AM335x
processor family. The TPS65910 device can power theAM335x family of processors supporting 300-, 600-,720-, 800-, and 1000-MHz frequencies. Of theAM335x solutions, the TPS65910 has the largest
amount of rails, making it a full-system PMIC.
Specifically, the TPS65910x device provides three
DC/DC converters and nine LDOs. This gives theTPS65910x device the ability to power an entire
system, including the processor and systemperipherals. An example application where a fullsystem PMIC might be needed is in video surveillancesystems. Video surveillance systems require power
hungry processors as well as many peripherals suchas microphones, speakers, LCDs, and wired orwireless connectivity. The biggest benefit of theTPS65910 device is that it can integrate a full system
into a single package to reduce the number ofcomponents and overall solution size.
TPS65217 – Included Linear Charger PMICThe TPS65217x device is a single-chip PMIC
designed to power the AM335x in portable and linedpowered (5 V) applications. The TPS65217x device
can power the AM335x family of processors
supporting 300-, 600-, 720-, 800-, and 1000-MHz
frequencies. The PMIC features three DC/DC
converters and four LDOs, and a linear charger. Of theAM335x solutions, the TPS65217 device is the only
solution with a linear charger, making it perfect for
portable battery-operated systems. Discrete battery
charger circuits can consume valuable board realestate. When combining discrete power regulators,power-up and power-down sequencing, and a discrete
linear charger circuit, in addition to accounting forspace between discrete components, fitting a discrete
power solution in a small area can be challenging.
Portable battery-operated systems like blood glucose

2AM335x PMIC Selection Guidemeters, which might have limited board space, canbenefit from the TPS65217 device because thedevices integrates all the necessary DC/DC
converters, LDOs, sequencing, and the charging circuit
to provide an overall smaller power solution.
TPS65218D0 – Lowest Power Consumption PMICThe TPS65218D0 device is a single-chip user
programmable PMIC that powers the Sitara AM335x
processor family for portable (Li-Ion battery) and linedpowered (5 V) applications. The TPS65218D0 device
can power the AM335x family of processors
supporting 300-, 600-, 720-, 800-, and 1000-MHz
frequencies. Of the AM335x PMIC options, theTPS65218D0 device supports the lowest power
consumption mode for the AM335x (Real-time clock[RTC]) compared to the available options, making it
the most power efficient. The TPS65218D0 device
provides five buck converters, one LDO, three load
switches, and a buck-boost converter. TheTPS65218D0 buck-boost converter is useful for 1-cellbattery systems because of its ability to boost voltage
or buck voltage. 1-cell batteries have an output ofapproximately 2.7 V to 3.5 V. Because one of the mostcommon power rails is 3.3 V, the buck-boost converter
can increase or decrease the 1-cell battery voltage toachieve a regulated 3.3-V power rail in portableapplications. Another feature of the TPS65218D0
device is that it can also be powered by a back-up
battery. In low-battery scenarios where data canpotentially be lost, a back-up battery ensures thatimportant data is saved and maintained. An example
where a back-up battery support is desired isElectronic Point of Sale (EPoS) systems. EPoSsystems record what sales are made, and can takedata, process, and store the information for business
transactions. If a scenario occurs where the system is
disconnected from a power adapter or from a Li-ion
battery supply, the TPS65218D0 device can switch
between power supplies, ensuring power is maintained
so that important business data can be saved.
