Part Number: LM5155-Q1 Hi experts,
Below two circuits have some difference at FB pin design, I can understand the first one that the FB is connected in the middle of the resistor divider. But for the second one, I cannot understand why the FB is connected…
Hi Matt,
Thanks for using the e2e forum.
If the design is still in an early stage, I would recommend to switch to a device with the power-good functionality already implemented.
A similar device to LM3488 with functional Power-Good pin is LM5155. https…
Part Number: LM5155-Q1 Other Parts Discussed in Thread: UCC28C43-Q1 , , TIDA-01505 Hi team,
I'd like to know whether it is possible to use LM5155-Q1 in Traction Inverter application as back up power supply? Can it be used after the start-up circuit from…
Hi Mark,
Thanks for using the e2e forum. 1) The start-up voltage is required to turn on the device. The device draws its VCC from the Vout pin. This voltage is required to configure the output voltage setting and supply the gate drivers. Once startup is…
Part Number: LM5155 Can someone point me to a video or explanation of how to do this?
I downloaded the library which has the following files:
LM5155-Q1_TRANS.DSN
LM5155-Q1_TRANS.LIB
LM5155-Q1_TRANS._EVM.LIB
LM5155-Q1DSS_TRANS.OLB

Part Number: LM5155-Q1 Hi experts,
For EMI performance, is there any need to add a capacitor across the MOSFET as below when LM5155-Q1 is designed for a SEPIC circuit? Thank you.

Good day.
Customer want to confirm if the CS pin was not design to connect in the Rcs and Ccs. Kindly refer to attached image below.
Thank you and looking forward…
Part Number: LM51231-Q1 Other Parts Discussed in Thread: LM51551-Q1 , LM51551 , LM5155 Tool/software: Dear Sirs,
we are not sure if we can use LM51231-Q1 to design a rather unusual boost converter:
Vmin = 2.5V Vnom = 3.3V Vmax = 3.7V Vout = 20V Iout = 3A
It…
Part Number: LM5155-Q1 Hi experts,
I downloaded the LM5155-Q1 Pspice Transient Model from ti.com and it can be opened with Pspice for TI successfully. However, when I click Run Simulation. It pop up below information and the simulation is aborted. Could…
Part Number: LM51501-Q1 Other Parts Discussed in Thread: TPS61071 , LM5155 , LM5157 Tool/software: Hi,
The waiting time from the start of the boost to the peak voltage is about 55.6ms after the switch is triggered. Our customer requested that this period…
