Other Parts Discussed in Thread: TPS65073 , OMAP3530 Hi,
I'm currently designing a OMAP3530 system, powered with a TPS65073. From the block diagrams in several data sheets (e.g. page 9 of SLVA376) I see the DCDC2 and DCDC3 enable signals tied together…
Other Parts Discussed in Thread: TPS65073 Hi,
somehow I cannot find anymore the PSP internal community list anymore. If someone could point me to it, that would be great. In the meanwhile I thought I post here.
Could someone comment on how the…
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…
Other Parts Discussed in Thread: AM3505 , TPS65023 , TPS65073 Hi,
I our application the power sequence is designed as per the Reference Design (SLVA411). In which VDDS(1.8) is ramped up first and VDDSHV(3.3) next and then VDDS_SRAM_xxx(1.8) as shown…
Hi Terry,
If customer is copying an existing design, they can continue to use TPS65950. It is NRND because support for this part is limited similar to the support for all OMAP3 based processors.
The processor overview page (which is also no longer…
Hello Patrick,
There is an application note available that details how to power the OMAP35x using the TPS65073.

Other Parts Discussed in Thread: TPS65073 Hi,
I need the DCDC1 of TPS65073 at 3.3V at startup (default: 1.8V). If I use an external resistor divider (e.g. 1k5:1k8), the 1k8 resistor is in parallel to the internal resistor divider (which I can not disable…
If the TPS65073 touch screen controller is not used, connect
AD_IN1 (TSX1) to ground
AD_IN2 (TSX2) to ground
AD_IN3 (TSY1) to ground
AD_IN4 (TSY2) to ground
Bypass and INT_LDO still need their recommended capacitor connected to maintain…
If the TPS65073 wLED (white light led driver) boost is not used, connect
ISET1 with a 100kohm resistor to ground
ISET2 with a 100kohm resistor to ground
ISINK1 to ground
ISINK2 to ground
FB to ground
L4 to ground
Other Parts Discussed in Thread: TPS65073 , TPS650732 , TPS40200 , TPS65070 , TPS65950 , DM3730 Question :
The TPS6507x datasheet does not explain the operation of the Power Path in detail.
Can you please explain how the Power Path is regulating…
