Part Number: TPS61251 Hi Team,
Could you help our customer. We need support regrading tps61251.
Here is their concern below.
I have a circuit but not getting desired result. So I am using to boost the battery voltafe which is 3.3-4V to get 6V using the…
Part Number: TPS61251 hi Teams:
Can the PG pin of tps61251 be directly grounded without use?
Will it lead to increased power consumption or quiescent current?
Hi Ahmet,
Another point when using TPS61251 for motor driver IC is manually force motor reverse rotate. Reverse rotate could produce a back electromotive force and charge up Vout. When Vout is charged above TPS61251's abs max rating (7V), the device could…
Part Number: TPS61251 Hi,
I think TPS61251 achieve load disconnect function by the PFET with its body diodes facing each other.
but I'm not sure the symbol shows the actual structure of PFET or means kind of function for load disconnection (like back…
Part Number: TPS61251 I used TPS61251 to regulate the voltage from 3V6 lithium thionyl chloride battery to 3V3DC. The circuit is exactly based on Figure 6 page 12, but I have R1 = 500kOhm. The output 3V3DC is connected to the LTE module. When the LTE…
Part Number: TPS61251 Other Parts Discussed in Thread: DRV8837 Hello,
I have an application of using the TPS61251 with the DRV8837 and I am seeing almost 7V on the SW node. I see 7V is the abs max spec for the TPS61251, is there any sort of diode clamping…
Part Number: TPS61251 Other Parts Discussed in Thread: TPS61073 I am using TPS61251 for the following specifications:
Vin = 3.6 - 5V
Vout = 5.5 V
Iout = 50mA - 400mA
The circuit diagram of my circuit is as shown below -
The type of components used are…

Hi TI Support,
In TPS61251 datasheet table paragraph 8.5 the shut down current is given as typical 0.85uA for the first time and as soon as power-good is triggered then the shut down current increases.
Question: What would be the…
