Part Number:LM5036
Hi !
I am building a GaN FET based half-bridge converter with the controller LM5036. The parameters are:
1. Input Voltage: Vin=36-75V DC
2. Output Voltage: Vout=28V
3. Output Current : Iout=10A.
4. Frequency: fsw=1 MHz
I have a few questions:
1. The VCC of LM5036 is from 8V to 16V, so its outputs (HSG/LSG) can not directly drive GaN FET .Designed to drive GaN FET using LMG1205, HSG and LSG are connected to LMG1205's HI and LI respectively. Is that appropriate?
2. The fsw is 1MHz and oscillator frequency is 2 MHz, is there a special requirement for opto-coupler between primary and second? Can I use the PS2811-1 which is used in lm5036EVM-294? If not, do you have some to recommend?
