Part Number: LM5155-Q1 Other Parts Discussed in Thread: UCC20225 , LM5155 Hi team,
1 . Customer can’t find the calculation of R UVLOS and C UVLO, can you please show me how to calculate them .
2.Could you please send me the internal resistance of Gate…
Part Number: LM5155-Q1 Hi expert,
In the flyback topology of the LM5155-Q1, the internal power dissipation of the device can be decreased by supplying the VCC using an additional transformer winding. Is this additional transformer winding power supply…
Part Number: LM5155-Q1 Other Parts Discussed in Thread: LM5155 , LM51551 , hi team
as we know, lm5155 doesn't have hiccup protection function. i find the below block diagram in the datasheet.(i know there is no "optional hiccup mode" module in LM5155).…
Part Number: LM5155
Hi,
I am planning to design a single 3.6V Li-ion battery boost converter circuit to output 12V, 10W with UVLO and hiccup.
I was searching the datasheets and reference designs.
The reference design of LM5155 seems good to start with…
Part Number: LM5155 Hi everyone,
I am using LM5155 for boost Converter design. The input is 3.6V and output is 12V/0.5A. The design runs good at low temperature but the current drain from power supply keeps increasing when temperature is above 220F and…
Part Number: LM5155 Other Parts Discussed in Thread: LM5157 , , LM5156 Hello TI Engineers,
Currently the LM5155, LM5156 as well as the LM5157/5158 SEPIC EVMs use coupled inductors in the layout. Based on the TI article "Benefits of a coupled-inductor SEPIC…
Part Number: LM5155 Hi,
I am currently using the LM5155DSSR in the boost converter topology with Vin of 24.0V, Vout of 36.0V, and Iout of 4.0A for stepper motor supply application.
Do you know how to eliminate or reduce the switching noise getting conducted…
Part Number: LM5155 Hi Team,
Could you please let me know who is the right AE window for this device? Customer would like to have a schematic review, checking the design of inductor, MOS, diode, input/output capacitor. Previously, I have provided calculator…
Part Number: LM5155 Hello TI Engineers,
I would like to know if you have any guide documents on the layout of the LM5155 SEPIC design. Do we just based it on the LM5155 SEPIC EVM? Do you have the Gerber files for that board?
The EVM is only a 2 layer…
