Part Number: VOLT-DIVIDER-CALC It is hard to believe that a design aid as poor as "VOLT-DIVIDER-CALC" should exist on TI's otherwise excellent web site.
1) The first thing I noticed is that it often gives answers that are plain wrong. For…
Hello Foong Wei Seng,
Here you can find the accuracy of the feedback node in PFM as well as in CCM: TPS63070 datasheet | TI.com
The output accuracy is dependent on the feedback node accuracy and the resistor divider accuracy. This tool helps to calculator…
Part Number: BOOSTXL-DRV8320RS Hello, We are using the BOOSTXL-DRV8320RS and TMS320F28004x with a very small low power motor, roughly 1.8 watts. The motor voltage is 12V and draws roughly 0.15 amps @ 4000 rpm. Max motor current is 0.620 amps.
I see that…
Part Number: TMS320F280039C Other Parts Discussed in Thread: SYSCONFIG Hi TI Team
I am trying to read AC volts through ADC on my TMS320F280039C, my AC volts input comes from output of my op-amp and i can see my sine wave and i have set 1.65 V DC offset…
Hello Bhuvaneshwari,
I used an excel-based load switch tool available at the link below to calculate the conduction losses in the FETs. This tool does not allow for paralleling FETs but you can simply divide the current by the number of parallel FETs…
Part Number: AMC3330 hi,
in sbaa553 277V is rms voltage and must be divided by 0.7 for peak voltage
therefore peak voltage will be 277/0.7 = 395 Vpeak
and then VLL is about 1.7 * 395 = 671 volt
are i'm true?
best regard
Part Number: TPS7B81 I'm using the TPS7B8133DRVR a 3.3V Linear LDO Regulator. I'd like to put a resistor divider up to IN(PIN 1) from the EN(Pin 2) pin. I'd use a 22Kohm between IN and EN pin then divide it down with a 6Kohm resistor to ground…
Part Number: TPS563209 Other Parts Discussed in Thread: TPS562209 , , TPS563200 Hi
The combined datasheet for TPS562209 and TPS563209 ("SLVSCM5A –SEPTEMBER 2014–REVISED NOVEMBER 2016") states:
"IVFB VFB input current 0 ±0.1 mA…
Part Number: BQ34Z100-G1 I have inherited this design. This design has been in use for a few years with no issues that I have heard about. We got a new batch of Lithium-ion batteries and new battery monitor boards. The BQ34Z100-G1 on our monitor board…
Other Parts Discussed in Thread: TL494 Hello evereyone, I want to design a dc-dc converter by rectifying the ac voltage. I will use the TL494 integration as the PWM control integration.
But I could not understand how to obtain the voltage to feed the i…
