Hi, I'm Nebi.
I have a question about LTC-3862 Multi-Phase Current Mode Step-Up DC/DC Controller.
This IC can operate multi phase operation for 2,3,4,6 and 12 phase operation. There is a 6-phase application example in the datasheet, but there is no 12-phase operation example. The datasheet does not give how to connect the PHASEMODE pins of 6 ICs for 12-phase operation.
Could you explain how to connect the PHASEMODE pins of the IC for 12-phase application?
I'm doing a 12 phase application but the phases don't shift 30 degrees. For this reason, current sharing is not correct.
Do you have experience with this, what would you suggest as a solution?
Additionally, the CLKOUT signal is not exactly a pulse wave like square wave. The CLKOUT signal is in the form of a ramp. This ramp is also observed in the DC2006A-A code demo circuit.
Does the unevenness of the CLKOUT signal also disturb the phase shift? What would you recommend to fix the CLKOUT signal?
