Part Number: LM2642 Other Parts Discussed in Thread: LM27403 , LM27402 Hi there,
I want to add a 12V backup power supply for my PC mother board. My target output power is 12V 33A, input from a suitable battery from 10-14.4V.
Because there's no multi-phase…
Other Parts Discussed in Thread: LM2642 I'm working on a twin power source (2 x 17V @ 5A) using the LM2642 chip. Each channel works perfectly when the other is disabled, although I did find a considerable difference in compensation requirements between…
Other Parts Discussed in Thread: LM2642 , LM5642 , LM5642X Hi,
I'm trying to understand the difference between LM2642 and LM5642/LM5642X:
* Switching frequency (300kHz vs. 200kHz vs. 375 kHz)
* Vin voltage range
* Duty cycle range
* LM2642 has PGOOD…
Part Number: TPS51222 Other Parts Discussed in Thread: LM2642 , TPS51220 I note that the TPS51222 has two outputs with 180 degrees of phase difference. I wonder if we can combine the two outputs together to generate a larger current output. I failed to…
Other Parts Discussed in Thread: LM2642 , LM5642 , LM5642X Hi,
I would like to connect one or two DC PSUs to a buck switch in order to get both voltage level conversion and current sharing into 12V, 2*15A.
Am I right to suppose that a dual current-mode controller…
