Tateo-san,
The DC voltage is about 6V on Cboot capacitor in normal operation, for the cap you meantioned above, the effective capacitance will be 50nF with 6V DC bias voltage. this is still OK for LMR14030 operation.
Part Number: LMR14030-Q1 Dear support team
Could you provide thermal data of below condition?
◆LMR14030-Q1
・Vin=12V Vout=3.3V Iout=2.6A @105℃
・Vin=12V Vout=3.3V Iout=2.6A @25℃

With the help of above part,i need to design 5V/200mA from the input of 16V.I selected inductor value based on the formula given in the TI datasheet and it is 85uh around.inductor ripple is considered as 0.4*Iout.
Output capacitor…
Part Number: LMR14030-Q1 Other Parts Discussed in Thread: LMR14030 Hi team,
Can you review the following configuration of LMR14030?
-. Is it possible to change the two resistors from 100kohm to 300kohm to reduce the power consumption?
Thanks…
Hi sir,
As per our customer requirement we need to add CLCLC filter on battery power circuit. So if you have any material related to CLCLC filter design please share us.
Hi Morgan,
You should be able to use the model from here: http://www.ti.com/product/LMR14030/toolssoftware
Use the " LMR14030S Unencrypted PSpice Transient Model " and then import it into TINA-TI so that it will create symbol or .TSM that you can…
Part Number: LMR14030-Q1 Other Parts Discussed in Thread: LMR23625-Q1 Hi,
Does TI have reference design / layout for the LMR14030-Q1 & LMR23625-Q1 that have been tested to CISPR25 compliance?
Thanks and Regards,
Part Number: LMR14030-Q1 Dear team,
Could you please tell me what are the values of IOH and IOL? In this way I can compute the Cout according to the calculation formula.
Thanks & Best Regards,

Part Number: LMR14030-Q1 Hi team,
In LMR14030-Q1 datasheet, the shutdown current is specificed at EN=Low as below.
Does the shutdown current (1~3uA) include the EN PIN (internal pull-up) current (1uA)?
Thanks,
Sam Lee
Part Number: LMR14030 Hi
There is comparison of behavior of DCM and CCM mode on the figure 25, 26 of datasheet.
Is there any condition so that the switching frequency is same between these two mode?
Because we got the result of being decreased…
