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-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 Other Parts Discussed in Thread: LM5160-Q1 , LM5160 , LM5156 , PMP20904 Hi team,
My customer is looking for a solution:
Input 12V
Output -17V~-24.5V adjustable
Can LM5160-Q1 achieve this?
If not, do you have any other suggestion?
Part Number: LM5156-Q1 Other Parts Discussed in Thread: LM5156 Hi Team I am trying to use average LTspice model of the mentioned part no. The model .lib file says "The model takes the inductance (L), Current sense Resistors(R4, R5 & R6) and Mosfet ON resistance…
Part Number: LM5156-Q1 Hello Team,
My customer use LM5156-Q1 as a first step power supplier. They are care about the Standby power consumption.
so, my question is, could we use UVLO/SYNC pin as an enable function pin to controll the chip enter the disable…
Part Number: LM5156-Q1 Other Parts Discussed in Thread: LM5156 Hi Team
There is good news that we DIN LM5156-Q1 again!
Please help confirm the design is good! THX
1.Vin is 12V
2.Vo is 18V
3.Io is 2.5A
4. Now C69 change to 1500pF. R5 change to 10ohm.

Part Number: LM5156-Q1 Dear team, I have one question in datasheet of LM5156QDSSRQ1. Could you please let me know if "open" curve can be observed between Pin1(BIAS) and Pin4(GND) during verification of IC? Thanks!
Part Number: LM5156-Q1 Other Parts Discussed in Thread: LM5156 Dear Representative!
In our new automotive project we need to have DC/DC with Vin: 8-32VDC, Vout: 195VDC. Iout: 0.07-0.1A. No isolation.
I choose 2 stage schematic: 1): Boost from Vin(8-32VDC…
Part Number: LM5156-Q1 Hi team,
Thanks for your support always.
In this case LM5156-Q1 is supplied power to sensor that Vin = 12V to Vout = 18V. Since our customer system has a request need < 0.1mA when system is standby. If I disable sensor still have…
