Part Number: LM25190 Other Parts Discussed in Thread: LM654B0-Q1 Hello,
I am searching for a CC-CV part that can deliver high power (50W to 100W). I have used the LM25190 to deliver ~10W but have not tried pushing it past this point.
Operating CV…
Part Number: LM25190 Hello,
I am using the LM25190 CC-CV buck regulator to drive a laser diode.
I am able to get expected Vout (1.8V) using custom FB resistors. I am able to set current limit using V-ISET from 0V to 1V.
I am unable to enter CC mode…
Part Number: LM25190 Hello,
The design uses an LM25190 to provide a 12 V / 8.3 A power supply, with an output adjustable from 0.9 V to 12 V.
When the load increases to around 7A, the output switching frequency drops to about 20 kHz. What conditions…
Part Number: LM25190 Tool/software: Dear TI Support Team,
In the LM25190 description, it states that tying FB→VCC selects a 12 V fixed output and tying FB→AGND selects a 5 V fixed output (see Table 6-1).
It also notes that this configuration is latched…
Part Number: LM5190QEVM-400 Other Parts Discussed in Thread: LM25190 Good morning,
I would like to ask whether it is possible to obtain the design files (schematic and PCB layout) of the evaluation board in Altium Designer format. I would need them…
Part Number: LM5148 Other Parts Discussed in Thread: LMG708B0 , , , LM5190 , LM25190 Hello,
I would like to drive the FB pin directly with an amplifier. Is this possible? I need to implement a current regulation loop .
Kind regards, David TURCHI
