Part Number: TPS51120 I am using BSO150N03MDG Mosfet instead of IRF7821.
When we will on the supply due to mosfet power supply is sorted, after off the supply and remove the mosfet from pcb, power supply is not longer shorted.
Also the resistor at the…
Part Number: TPS51120 Circuit for design of regulation using TPS51120 is similar to the datasheet. It is working in 2 of the boards.
But in 3rd board, CH-1 output of 5V is generated for 100msec and is dropping to 0V. EN1 is still high during this time…

How to adjust the TPS51120 Vout1 and Vout2 voltage?
The datasheet say this is adjustable, but the setting formula is not clear.
Thanks

Part Number: TPS51120 Hello.
I have some questions about capacitor selection. (Please see Figure 28 of TPS51120 data sheet.)
(1)
If a capacitor of 1 uF is selected as in the data sheet for C51, the capacitance will be 0.575 uF due to the DC bias characteristic…
Part Number: TPS51120 Hi,
I am using a TPS51120 to give a 5V and a 3V3 to my system from an unregulated voltage (12-24V). I observe a lot of electromagnetic disturbances
(radiated for sure, conducted maybe) and it seems that they come from the TPS51120…
Part Number: TPS51120 Hi Team,
I had used TPS51120 in my project. The schematic and MOSFET design as below.
Depends on my design, may i know how to calculate the efficiency of each power rail (5V and 3.3V)? Do you have any calculated tool can share with…
Part Number: TPS51120 Dear Team,
Can you please see customer question below and advise ?
U22 (on schematics) gets damaged on power up.
The power up sequence includes two stages:
3_3_ALW and 5V are turned on (light load – CPLD and some pull-up resistors…
Part Number: TPS51120 Other Parts Discussed in Thread: TPS51220A-Q1 G'day,
I'm using the TPS51120 as part of the power management solution for an automotive device. The device is powered directly from the battery as follows (VBATT_FILT connects to…
Part Number: TPS51120 Hi,
I have a 12V source, which I'm voltage dividing down to 4.4V, which is then connected to both EN2 and EN5. I've verified that 4.4V is present at the output of the voltage divider. However, when I connect the voltage divider output…
Part Number: TPS51120 Other Parts Discussed in Thread: CSD17527Q5A , , CSD17506Q5A Hi Sir,
We do glitch test for L/S gate by TPS51120 with CSD17527Q5A and CSD17506Q5A.
Below is capture waveform. May I know has any risk for MOSFET? Looks voltage is threshold…
