Part Number: TPS65070 Other Parts Discussed in Thread: TPS65072 , TPS650732 , TPS650731 , TPS65073 How should I connect/terminate un-used pins on the TPS65070?
The TPS65070 shares a datasheet with the TPS65072, TPS65073, TPS650731, and TPS650732. Does this…
Other Parts Discussed in Thread: OMAP3503 , TPS650731 Hi All,
We are facing a very strange issue on my OMAP3503 based issue.
We are using OMAP3503 CBC package and TPS650731 PMIC. And LDO2 of this chip is used to supply the power to OMAP VDDS_MMC1 domain…
Other Parts Discussed in Thread: OMAP3530 , TPS65073 , TPS650731 Hello,
I am looking to see if anyone has used an OMAP3530 without coupling it to a TPS65690. I realize this is a more challenging design, but would be interested to discuss this
path.

Other Parts Discussed in Thread: TUSB1210 , OMAP3530 , SYSCONFIG , TPS650731 , TPS65950 , OMAP3525 I'm looking for some clarification on Advisory 3.1.1.193 in the March 2010 revision of the OMAP35x errata.
The advisory states that the SMSC USB3320 PHY…
Other Parts Discussed in Thread: TPS65073 , OMAP3530 , TPS65920 , TPS650731 Hi!
I'm designing an OMAP3530-system which only requires a simple PMU so I think the TPS65073 would fit well.
However, the design-in Wiki and the TPS6507x documentation is a…
These bits only mask the PGOOD pin output. The status of the supply is indicated by the contents of register PGOOD (address 0Bh) and the PGOOD pin output if the bits are unmasked.
Please use part number followed by subject of question in your posts.…
Undervoltage lockout will shut the device off when the input goes below Vuvlo, 3.0 V for example.
If you set the hysteresis to 500mV, the device will not turn back on until the input goes above 3.5 V ( Vuvlo + Vhyst ).
UVLO is to prevent the device…
Per our conversation, I understand you have an I2C bus in your system but it will not be active while the system is in the sleep mode.
Before your system goes into sleep mode, you can set CON_CTRL1[7:5]=101 so that DCDC converters are enabled individually…
Also note, t he contents of the registers (including CON_CTRL1) will be reset to the default values as
defined in the datasheet, if the TPS65070 input voltage goes below UVLO or PB_IN
is held low for 15 seconds.
