Part Number: TPS628502-Q1 Tool/software:
Dear TI support,
We are using TPS628502QDRLRQ1 as Buck from 3V3-1V2 with current output load up to 2A
Here below the detailed schematic
We observe 3 unexpected behaviors according to the configuration mode…
Part Number: TPS628502-Q1 Tool/software: HI BU team
My customers don't understand well on current limit and foldback current limit in tps628502-Q1 datasheet. Would you help provide below information?
1. The advantages and disadvantages
2. The diagrams…
Part Number: TPS628502-Q1 Tool/software: The thermal shutdown function is explained in the datasheet as follows: "The junction temperature (TJ) of the device is monitored by an internal temperature sensor. If TJ exceeds 170°C(typ), the device goes…
Part Number: TPS628502-Q1 Tool/software: I'm using the TPS628502-Q 1 PSpice transient model and would like to determine the phase margin and dB gain. However, in my steady-state simulation, the dB gain of the output voltage is very low. I am probing…
Part Number: TPS628502-Q1 Tool/software: Hi Team,

If you need any more information, please let me know.
Sw Freq 2.25MHz
Max ambient temperature. 85 ‘C
Part Number: TPS628502-Q1 Hello there,
I am measuring a huge overshoot on the SW node of the TPS628502-Q1.
Vin 4.2V, Vout 3.3V, Iout=0A, FPWM mode.
Trise 0.7us, Vpeak=6.46V. Is this normal behavior for the device? 2.2V overshoot is huge.
This measurement…
Part Number: TPS628502-Q1 Hello Team,
Good day
We are using TPS628502-Q1 part in our design for 3.3V to 1.2V conversion. We have a requirement that output voltage ripple should be less than 6mV. But while measuring in DSO we are getting around 12mV pk…
Part Number: TPS628502-Q1 Hello Expert,
I have question for Table 9-1 on datasheet.
This table has minimum output capacitance for each output voltage setting and comp setting. Then, could you please tell me about whether it is rated capacitance or actual…
Part Number: TPS628502-Q1 Other Parts Discussed in Thread: TPS628502 Hi Experter,
currently our design for TPS628502.
there is a 4.7K ohm resistor between VIN and MODE/SYNC.
if change it to 47k ohm to reduce power consumption.
do you have any concern…
