Part Number: LM5155-Q1 Tool/software: Hello team,
Good day!
There is a using case of LM5155-Q1, VCC is about 6V, and the gate voltage is 6V as well, but this voltage is not enough to drive MOS, so do you have methods to improve the drive voltage?
Thanks…
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 Hello team,
I need to check what is the highest boost ratio when use LM5155 as Sepic topo.
In the datasheet, when RT=220k,
if Dmax=90% (min), the boost ratio is 9,
if Dmax=93% (typical), the boost…
