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…
Hi Dustin,
Dustin Yim said: What is the best option (1 or 2) for 3* 10uF? Since customer dont want to add cap but want to enable SSC.
For SSC enabled config, recommendation is 30uF.
If the customer wants to use a lower Cout, I would suggest to confirm…
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 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: TPS628502TPS628502MDRLR is the fixed 1.8V output version. What is the function of the FB pin in this case? Should it be left unconnected or should it be connected directly to Vout? Datasheet isn't clear how to use the fixed output voltage…
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…
