Other Parts Discussed in Thread: DRV8837
Helping a customer come up with a low current boost circuit. Need a voltage tripler to go from 3.3V to >7V for bias to an LDO to end up at a clean 6.0V.
Below is a logic gate version I came up with using TINA.
I'd like to replace the XOR gates with the outputs of the DRV8210, then use the PH input to drive the outputs 180 degrees out of phase to operate to charge pump.
Any concerns doing something like this? Do you have a SPICE model you could send me (internally is fine) that I could use to model this? Thanks! -Steve
