Part Number: TPS62148 Other Parts Discussed in Thread: TPS563208 Hi team
I want to know switching frequency vs input voltage is change depended on output voltage like TPS563208 (datasheet p7, figure7) or not.
If there is some data please share with…
Part Number: TPS62148 Q1: The internal Vref is 0.7V (used for SS/TR) typical, right?
Q2: I understand SS/TR is connected to a Current Source, which is connected to a mid-rail that comes from VIN - yes? I am being asked for a high-level visual description…
Part Number: TPS62148 [Captured Waveform]
As you can see in the attached waveforms, there is ~150mV of "drifting" observed on the input.
Q1: What could be causing this "drifting" at Vin? Q2: Will such a high "drifting" at the input cause any trouble…
Part Number: TPS62148 Could someone tell me how to externally add phase compensation to the TPS62148?
I am seeing a design case where an FRA(frequency response analyzer) is used to apply a sine wave to the FB pin, and the phase margin is only 30deg…
Part Number: TPS62148 Hi
Could you please tell me that reason why the switching operation is left stopping by the back-EMF due to stopping of the motor and the SW node is in Hi-Z even if TPS62148 works with the forced PWM mode. I would share the detailed…
Part Number: TPS62148 Hi,
The output voltage rises up to the input voltage by the back electromotive force which is generated when the dc motor which is the output load for TPS62148 is suddenly turned off with the forced PWM mode. At this time, the…
Part Number: TPS62148 Hi Team,
One quick question.
What is the status of the PG output when EN is set to low (device disable condition)?
Regards,
Takashi Onawa
Part Number: TPS62148 I was hoping for some help regarding the 100% duty-cycle operation of the TPS62148 for 5V output.
1) Figure 80 from the DS shows around 700kHz switching frequency before the graph ceases (device enters 100% duty-cycle mode?)…
Part Number: TPS62148 Other Parts Discussed in Thread: TPS62480 Hello experts,
I got question about layout from customer.
My customer want to move vias from datasheet recommendation as below.
In this case, we need to move C1/L1 due to vias location…
Part Number: TPS62148 Hello experts,
I got question about GND solid pattern under inductor from customer. Could you give me advice?
In generally, it is better to remove GND solid pattern under inductor because it may cause noise influence (e.g…
