Part Number: LM5156 My Team is designing a DC:DC Boost power supply with 3.3~3.65VDC input (power cell Li-Ion battery able to supply up to 30A for short bursts).
The output stage needs to generate 23.0+ VDC @ 1.5A for a maximum of 30 seconds.
We've started…
Part Number: LM5156-Q1 In the application note, it is stated that the maximum inductor ripple current occurs when duty = 0.33.
If the minimum duty in my operating conditions is 0.36, should I use 0.33 or 0.36 when calculating the inductance?
Part Number: LM5156-Q1 My design is Vin=8~16,Vout=25,Iout=0.18,eff=90%,fsw=440k current ripple=30% in CCM mode.
The value of ILpk shows 1.53.
Iin_max is 25*4.5/8/0.9=0.68,if the value of ILpk is 1.53,it means the ripple current of L is 0.85,so the ripple…
Part Number: LM5156 We're looking to utilize the 5156 to boost a Li-on Power Cell (typical operating voltage is 3.3v @ 30A) up to 24v +/-2.0v at 3A for up to 40 seconds, then shuts down. I wanted to enter this data in the 5156 Boost calculator worksheet…
Hi Yee,
Sorry for the delay. I have checked our reference design library but did not find a reference for this exact application.
However, this design should indeed be possible with LM5156. To create a dual output flyback application, you can use the k_break…
