Part Number: TPIC74100-Q1 Hi,
We'd like to use a buck-boost like the TPIC4100 to always keep the output voltage 5V. When the input is lower, boost it to 5V. When the input is higher, buck the signal to 5V. The problem is that it looks like the minimum…
TPS55065-Q1 has output current of 0.5A where as TPIC74100-Q1/TPIC74101-Q1 have output current ratings of 1A. Between TPIC74100-Q1/TPIC74101-Q1, I do not think of any difference other than switching frequency.
If you look at below link, there is…
Other Parts Discussed in Thread: TPIC74100-Q1 I would like to confirm the transition time from buck to boost and from boost to buck for TPIC74100-Q1.
How much is the time?
What is the cause TPIC74100-Q1 has the transition time?
The customer checked it…
Other Parts Discussed in Thread: TPIC74100-Q1 I would like to confirm the impedance of CLP pin for TPIC74100-Q1.
How much is the impedance?
Or is there pull down resistance or pull up resistance in the IC?
The customer want to know it for connecting MCU…
From a customer, it is a question about standby current. The standby current value of TPIC74100-Q1 is required. Conditions are the voltage of Vdriver at the time of 6V to 18V. The value is if satisfactory if it is about twice or less times of the value…
Other Parts Discussed in Thread: TPIC74100-Q1 I have confirmed the output capacitor for TPIC74100-Q1.
In the application note (SLIA083), there are conditions of output capacitor (value and ESR).
And in the user's guide of TPIC74100-Q1 EVM (SLIU002), there…
Other Parts Discussed in Thread: TPIC74100-Q1 I fixed waveforn in ramp up (add 1uF capacitor).
But there is the small peak in the power off.
I attacked the file.
I have questions of TPIC74100-Q1 .
The customer have checked the characteristics of TPIC74100-Q1 . I have attached the file of the wave form in the ramp up.
We did release the transient model for this part last month so maybe you can use this for your development and verification now: http://www.ti.com/product/tpic74100-q1 (look under "Tools and Software").
