Part Number: LM25088 Hello team,
please help me clarify some basic concepts: i have a working regulator based on LM25088 device, that i would like to use to charge supercapacitors. The regulator works fine if i connect it to a resistive load, but dramatically…
Part Number: LM25088 I'm working on a buck converter to step down 400V to 180V with a 1A max output current.
It seems that almost all of TI's buck controllers have built in drivers and none have an input voltage that works with a 400V rail. I would…
Part Number: LM25088 Other Parts Discussed in Thread: LM5088 , LM25148 I would like to utilise the buck controller to realize the negative boost converter (Negative input voltage to Negative output voltage non isolated DC-DC converter).
I found some…
Part Number: LM25088 Other Parts Discussed in Thread: LM5088 Hi, team!
I use LM25088(Buck) to produce -15V with TINA as shown in figure. But GND in chip(Pin 6) provides 8A current which formed a close loop with inductor, diode when switch is open. …

Hi Marc,
The key capacitor is C67 - this should be placed closed to the FET to minimize the switching loop area comprising the FET, diode and sense resistor. The lower parasitic inductance improves the performance of the circuit, allowing reduction…
