Part Number: LM22670 Hi Team, Our customer is looking for the theta JC value of LM22670TJE-ADJ. I've checked the datasheet however I only see theta JA. I would appreciate your help on this matter. Thank you and have a great day. Regards, Cedrick
Part Number: LM22670 Other Parts Discussed in Thread: LMR33630 , Hi team,
My customer tested to short 7pin(Vin) and 8pin(SW) with LM22670-5.0(HSOP). The condition is Vin=24V, Vout=5.0V.
As a result, the device got burn. I believe that the 24V is conducted…
Part Number: LM22670 Hi TI EE:
My buck power using LM22670MRE-ADJNOPB ,Vin:24V,Vout:15V .
I have trouble to make sure the divider resistor value.Please help to make sure the bellow figure which one is better.
Thank you!

Dear Yang,
Thanks for your reply!
I'm directly short the Vout to GND, and I have test the LM22670 EVM to evaluation, and the inductor is very hot yet. I think the waveform is weird also, So I don't know why the new design choose frequency current foldback…
Part Number: LM22670 Hi,
My customer hopes to set RT into 220kΩ to reduce switching frequency until below 200kHz.
What is the assumed problem when RT 220kΩ?
We're recognizing that RT is recommended until 200kΩ.
Best Regards,

Hi,
On the datasheet 7.3.5, minimum load is required as follows;
"A minimum load of about 5 mA is required to fully recharge the boot-strap capacitor in the minimum off-time."
Does the minimum load value depend on another…
Part Number: LM22670 Hi,
Follows are described on "8.2.1.2.2 Inductor" of the datasheet;
"To keep the application in continuous conduction mode (CCM), the maximum ripple current, IRIPPLE, should be less than twice the minimum load current".…
Part Number: LM22670 Other Parts Discussed in Thread: LM10011 , LM10010 Has anyone variably adjusted the Vout of the LM22670 using a programmable digital pot IC?
I was wondering if the high impedance indicated on the data sheet for the FB pin would prohibit…
