Other Parts Discussed in Thread: LM5009ALM5009A at 5V output (90v input) and 2mA of load current the Inductor gets HUGE (equation # 7)....8mH. Is this correct?
Other Parts Discussed in Thread: LM5009A Hello All,
As mentioned in datasheet of LM5009A, minimum capacitor of 0.47uF is required on VCC pin.
This introduces substantial delay for output to reach a final value.
If this pin is not supplying current to any…
Other Parts Discussed in Thread: LM5009A Started with an LM5009A Webench design: 10<Vin<45VDC, Vout=6.5V, Iout=150mA where R1=105K, R2=84.5K in attached schematic. Resistive load was applied to draw 100mA. Vin was started at 10VDC and stepped up by 2V…
Other Parts Discussed in Thread: LM5009 Dear specialists,
My customer is measuring the LM5009 that is using for the LED driver.
When he was setting RT=1.4Mohm, output response time became very long. It is good response when RT is 1M ohm. Please see the…
Other Parts Discussed in Thread: LM5009A , TINA-TI Hi.
I am trying to use the LM5009A for an inverting power supply. Input is 18-56V, output is 15V. Current 10 - 100mA.
When I turn on the input power, the output is -15V, for some time (1hour), after this…
Other Parts Discussed in Thread: LM5009 , TINA-TI Hi,
I've try to simulate the switcher LM5009 using TINA-TI Version 9.3.50.40 SF-TI. As a starting point, I used the example circuit in the datasheet LM5009 page 11.
The voltage at the switching node…
Other Parts Discussed in Thread: LM5009A , LM5008A , LM5009 , LM5008 , LM5007 Hi
I am working on a buck converter using LM5009A and LM5008A.
But the pSpice simulation model for the above ICs are not available in TI website.
Can anyone help me to get the pspice…
Other Parts Discussed in Thread: LM5009A , TINA-TI , LM5009 , LM5007 I am wanting to know if there are SPICE models available for the LM5009 and LM5009A Buck COT Regulator chips that can be utilized within TINA-TI?
I have used WebBench, but most of my other…
Hi Rolf,
Can you check that all of your components are correct for the LM5009A by plugging them into the webench on LM5009A's product page and see if it says any errors?

Other Parts Discussed in Thread: LM5009A , SM72485 , LM5009 Dear Sir
May I know what's different between LM5009 / LM5009A / SM72485??
I don't know which is TI focus and popular solution
Thanks
