Part Number: LM5155 Hi, Dear Appplication engineer
I'm using LM5155 to design a adjustable high voltage power supply based LM5155. the schematic as below figure shows. the input voltage is 12V. the expected output voltage is: +-5V ~+-100V. expected…
Part Number: LM5155 Other Parts Discussed in Thread: TL431 Hi Experts,
In LM5155 application note SNVA866A , what's the purpose of Rcomp and Ccomp which are connected Vcomp?
If it's for compensation purpose, how it contribute to Zero and Pole?

Part Number: LM5155 Dears:
Customer want to know if use LM5155 to do flybck in DCM mode, duty cycle is over 0.7. Do they need to do compensation ? Thanks.
Hi Ashot,
Thanks for the update. The low duty cycle indicates that the device runs in overcurrent protection (OCP). The device pulls down the gate signal after the minimum on-time as the voltage at the CS pin is above the OCP trigger votlage (100mV)

Part Number: LM5155-Q1 Other Parts Discussed in Thread: LM5155 Hi TIer
As shown in the figure below, the LM5155 circuit that we used previously was automatically turned on at power up. We now want to use the microcontroller to master the power supply…
Part Number: LM5155 Hello,
I am designing a SEPIC converter with the LM5155.
Therefore I am looking for the document "How to Design a SEPIC Converter Using LM5155". Where can I find it?
So far I have only found this one: https://www.ti.com/lit…
Part Number: LM5155-Q1 Customer would like to design with LM5155-Q1 for DCM Flyback. Could you please help share the related design tool? The tool in ti.com is for CCM.
Part Number: LM5155 Hi,
I using below condition on LM5155 webench but can't generete new design.
Would you please help check below condition is ok for LM5155?
Thanks!

Part Number: LM5155 Hello TI Engineers,
I am currently designing a 24 to 5.45V DC to DC converter using sepic topology i have used the quickstart calculator to design the circuit but the gate voltage seems to go down to zero after 5 microseconds. I have…
