Part Number: LM5143 Tool/software: HI
In testing customer's board, customer found that in the case of DCM (DCEMB is chosen) light load, the wave form of the SW illustrated the unstable operation of the LM5143, in order to understand the cause of the…
Part Number: LM5143 Tool/software: hi,
when 2 pcs of LM5143 are designed with multiple phase single output, how the secondary LM5143's DITH pin is connected?(in datasheet, DITH pin of 2rd LM5143 is float)?
Part Number: LM5143 Hi For Buck with LM5143 do we have to use a lower value sense resistor than 0.073V/I(peak), so that we make adequate room for the added slope compensation ramp?
Part Number: LM5143-Q1 Other Parts Discussed in Thread: TINA-TI Hi ,
I am planning to use LM5143-Q1 , LM31707 and LM6002 parts in my design and wanted to simulate the same in TINA-TI (free version) . The Pspice models available in your website are all…
Part Number: LM5143 Hi,
LM5143 datasheet seems to say that if no gate-source resistor, and that channel gets disabled (EN=0), then its hi side FET will end up getting turned ON and staying ON?
Part Number: LM5143
Hi,
[In another post you kindly advised that the COMP pin control voltage range was 0.3 to 2.5V.]
So, we are doing Dual single output Buck with LM5143. Each of the Bucks has 17vin, 15A out , 13.5Vout and 450kHz,
(L = 3.3uH, R(sense…
Part Number: LM5143 Other Parts Discussed in Thread: PMP31210 Tool/software: Hi,
A my account has some questions about schematic of PMP31210. pls kindly help to check them.
what purpose are D3/D4/D7/D8 Zener Diode? Can they be removed if peak voltage…
Part Number: LM5143-Q1 Tool/software: Hi,
I notice that datasheet points out output cap value is effective(derated) value. I wonder other capacitor value is effective value or rating value? Like input cap, boot cap and so on.
