Part Number: LM5122 Hi
I'm Frank
we met some problem for LM5122MHX used for LOW SIDE BUCK (as custermer requirement as Charger) Input 56V output 53.5V/10A
there is some question below
1. would you give me some advice if you have experince LM5122MHX…
Part Number: LM5122 V jedné z našich aplikací používáme 400W audio zesilovač ke zvýšení vstupního napětí a pohonu výkonu.
Výstupní výkon musí být omezen na cca. …
Part Number: LM5122 We use a 400W audio amplifier in one of our applications to increase the input voltage and drive the power.
The output power must be limited to approx. 400W. Limitation is done using resistors R280 + R290.
When I use Current sense…
Part Number: LM5122 Hello, Even LM5122 is under the bypass operation described in 7.3.9 of the datasheet, does the “Cycle-by-Cycle Current Limit” described in 7.3.10 still work? Or it works only during boost mode? Best regards, K.Hira…
Part Number: LM5122 Other Parts Discussed in Thread: LM5121 , LM5171
Hello,
I came across a similar question on the thread regarding the LM5122 current detection position ( Previous answer from TI Forums ). As was already answered, using CSP, CSN pins on…
Hello Jacob,
The rise and fall times on the LM5122 are specified with a load capacitance of 4700 pF. So dependent on the input capacitance of the circuit you have behind the HO, LO outputs, the rise and fall times will vary.
You can check in your circuit…
Hi Sean,
Thanks for the feedback.
1) There should be no problems with connecting several applications to the same GND over the board. As long as the other application does not inject noise into the analog ground of LM5122, I see no concerns here.
2) It…
Hello Deepak,
The wattage of the resistors is low as the input impedance of the sense amplifier is relatively high, so the standard 1/8th W should be sufficient.
1uF for CBST should be ok.
The 2nF capacitor in parallel to the RC compensation network seems…
Part Number: LM5122 Hello,
can you please Please help to evaluate max output power capability on one LM5122:
input voltage range 7.0V-18V, output 24V, output power 240W+
can you help to evaluate above condition if customer can use only one LM5122?
Thanks…
Hi Bhargav,
BHARGAV ITALIA said: Here is the wave form with Ch1= SS Ch2 =Vcc Ch3 =LO Ch3=HO
The noise pulse only appears on the first one or two startup attempts
I want to know what is the reference of HO? HO-SW or HO-AGND?
Please share SS, HO-SW, LO…
