hi ,experts
I use UCD9244 and UCD7242 to provide power supplies for TMS320C6678,but why the PWM pin of the 9244 is 1.65v, i kown this will shut off the high-side MOSFET and the low-side MOSFET,which will produce 0 output of the rails.who can tell me why?
when i produce a PWM wave (1MHZ,duty cycle=10%)to the 7242 without the 9244 pwm input to 7242,but i still get a 0 output.i can't understand the result,can any expert give me some advices?many thanks!!
