Part Number: LM25005 Other Parts Discussed in Thread: TPS54040 Hi,
I want to use the LM25005 as a negative Boost converter, Uin = 12V, Uout = -15V, I = 0.5A.
I attached the design pdf in this post.
My question is now, how can I manage to feed…
Other Parts Discussed in Thread: LM25005 , LM46002 , TPS5420 I have a question about LM25005.
Does this Ic have light load mode?
I am looking for the IC of PWM mode only.
Best regards,

Other Parts Discussed in Thread: LM22680 , LM25005 , LM5005 Hi Team,
Our customer would like to use CCM mode at output current = around 0A to 1.5A.
We understand that we can use CCM mode at light load conditions if we increase inductor value.

Other Parts Discussed in Thread: LM25005 Hi,
I would like to know what happens when the input voltage is less than the set output voltage in a LM25005 regulator?
I would like to power a BQ50050B circuit with input voltage ranging 10-28 volts, is their…
Other Parts Discussed in Thread: LM25005 There seems to be a bug/error in Webench for a negative DC-DC design using the LM25005. In my Webench design Cramp=56pF and L1 = 22uH. According to the data sheet, Cramp should equal 10^-5 * L1, so should equal…
Other Parts Discussed in Thread: LM25005 I used TI's webench design tool to generate -15V fixed output from 18-21V input.
The IC suggested was LM25005. Please see the attached file for design.
On my first test, i was getting -3.55V output.
on datasheet…
Other Parts Discussed in Thread: LM25005 I am looking for ICs that meets the following conditions.
Vin=15V
Vout=5V
Iout=1.5~2A
Switching Frequency=~500kHz
PWM mode only( we do not need Light Load mode )
Non-synchronous rectification

Nishazawa-san,
There is no way to simulate the loop characteristics for TPS54240 in the inverting buck boost configuration using the existing tools. You would have to estimate it by the non-inverting case, e.g. Vin = 18 V and Vout = 6 V. There are some…
