I need to drive 4 MOSFETs with PWM of certain set frequency, whose outputs are connected to batteries. These 4 batteries are in series. I need to isolate input and output. Can I use a single Isolated DC-DC converter to power all 4 opto-couplers. I am using TLP350 as gate driver.
The main reason for using single isolated power source is to reduce cost. If this doesn't work how else can I power multiple opto-coupler with low cost?
