Part Number: TPS84620 Other Parts Discussed in Thread: LMZM33606 Need 12Vin to 5Vout @ 6A power module design with 500 KHz switching frequency. 500 KHz is a mandatory requirement.
Couldn't find option to set TPS84620 to 500 KHz for above Vin & Vout…
From the waveforms, the input voltage is dropping when both output voltages are turning on. The current capability of your input supply may need to be increased. You may try delaying the turn on of the output voltage until VIN is higher by using the UVLO…
Other Parts Discussed in Thread: TPS84620 Hello,
In my design I'm using a TPS84620 to produce 2.5V and I want to make sure I get the resistor and cap settings correct.
On Table 1 it shows for 2.5V that Rrt should be set 1K ohm while Table 2. says…
Other Parts Discussed in Thread: TPS84620 Dear support team,
I decide the switching frequency of the TPS84620. Could you teach the calculation formula for determining the resistance value of the RT / CLK?
Regard. Bob Lee
Other Parts Discussed in Thread: TPS84621 , TPS84620 Hi All,
Can any one tell me reference voltage used in the feedback loop and its tolerance value for TPS84621 and TPS84620?
Thanks in advance.
Hi Jimmy,
Please note that the TPS84621 has a wider output voltage range, down to 0.6V. This is fully released and is completely pin-to-pin compatible with the TPS84620, and the same height dimensions.

Other Parts Discussed in Thread: TPS84621 , TPS84620 Hello,
Can the TPS84620 or the TPS84621 operate in current sharing mode like the LMZ2xxxx series?
Thanks
Hi Norbert,
It may be possible to configure this device as a constant current source similar to how you describe above. I would need to know more details of your application. I would also want to add in some protection for both the LED and the TPS84xxx…
There is not really a derating curve per se. The thermal performance is almost completely determined by the PCB design and other external operating conditions. The limiting factor is maximum junction temperature. The thermal parameters are in teh data…
