Part Number: TPS63031 I need to be able to operate this device at 125C ambient. I know the recommended Ta max is 85C.
Doing some power calculation I get that the max Pd is 0.41W at 125C
Pd = (Tj - Ta) / Rja = (150 - 125) / 60.7 = 0.41W

Hello Samir,
as soon the output capacitors are discharged you should measure 0V, if EN=Low.
Does this phenomenon happen on multiple devices?
Could you share the layout for a cross check?
Do you have any output load attached?
I see there is a…
Thanks for your prompt reply Milos.
Answer to your questions.
1. Yes, except for an added pull up in a completely different part of the circuit
2. PCB layout attached.
3. Will forward these if/when I can capture them
4. There is a thermal fuse…
Part Number: TPS63031 Hi everyone,
I am using several TPS63031 on a design to get 3.3V supplies. The EN pin of two of them is connected to the GPIO pin of a microcontroller and is pulled-down by a 10k resitor.
When the GPIO pin is configured to output…
Part Number: TPS63031 Hi,
I am using TPS63031 to power a 3.3Volt circuit from a Lithium ION battery of 3.7 Volt. The circuit is mostly in low power mode consuming 5uA current.
When I tested the current consumption of TPS63031, it seems like 5 mA is…
Other Parts Discussed in Thread: TPS63031 Hi Milos
1.What is the efficiency curve when the load is 1μA~100μA? Only 100μA or more of relevant data is available in the manual.
2.Does the chip have minimum load requirements? If the load is about 1μA…
Part Number: TPS63031 Hi,
I use the TPS63031 together with a MCU and cellular module. My system is battery powered by a Li-Ion battery (3.7V/2500mAh). When my system goes to sleep, the load (for TPS63031) is just 4-5uA. When I measure the current drawn…
Part Number: TPS63031 I have designed a board where I use the TPS63031. The input voltage is from a Li-ion battery (3.3 V to 4.2 V), nominal current is less than 5 mA and max current is 500 mA.
I use an inductor with a Isat = 1.29 A.
There is an audible…
