Other Parts Discussed in Thread: TPS40210-Q1 , TPS40210 I see that the TPS40210-Q1 manual supports flyback and SEPIC. Is there any application note or design reference?
Part Number: TPS40210-Q1 Other Parts Discussed in Thread: TPS40210 Hello,
The customer measured the actual device to check the SS signal rise time of TPS40210-Q1. (See attached file)
result, It was confirmed that it rise up in the order of VDD → BP…
Part Number: TPS40210-Q1 I am just starting to use this chip. I wanted a switching frequency around 150-170kHz and selected an RC combination of 220pF (NP0, 5%) and 499k (1%), based on Frequency-Resistance graph.
Surprisingly, I get 103kHz switching…
Part Number: TPS40210-Q1 Other Parts Discussed in Thread: LM5176 Hello team,
This is wide question about boost converter.
Now our automotive customer is considering to use boost converter as primary power supply.
The purpose is to output stable…
Hi Anilkumar,
Your modified circuit is wrong, and the inductor current cannot continue because D3 polarity.
To get a negative voltage from a positive source, you can use a flyback with a boost controller like the TPS40210-Q1, or use a inverting…
Hi Raghav,
Thank you for posting. The TPS40210 and TPS40210-Q1 are basically the same design, and the -Q1 version is for automotive qualified, which passed AEC-Q100 qualification. If you are not targeting the automotive applications, you just need…
Part Number: TPS40210-Q1 Hi Team,
If I am using the TPS40210-Q1 as a SEPIC instead of boost, do the following equations still apply in the same manner?
Thank you in advance,
Jared
Part Number: TPS40210-Q1 Hi,
When I used TPS40210-Q1 at low voltage input, i find that the VDS waveform is abnormal while short output start.
Topology: Flyback
Feedback: Primary side
Vin: 8~16V, (Abnormal only is happened at 8V input and 12V/14V…
Part Number: TPS40210-Q1 I'm looking at a design where there is a resistor that connects between the COMP pin and the FB pin of the TPS40210-Q1 and would like to know the peak and valley voltages of the ramp voltage that the error amplifier output (COMP…
Part Number: TPS40210-Q1 The following specifications are listed on the data sheet P5 of TPS40210-Q1.
What is the state of "no switching" described in Test conditions?
1) Period of High when PWM signal is driving. 2) Period of Low when PWM signal…
