Dear all
I use the UCD9224/UCD9248 chip, and I see the datasheet that mention the UCD924/UCD9248 can generate min 15.26Khz(switching frequency) PWM signal.
The datasheets also mention that the diver circuit is needed, like UCD7231 or UCD 7242 circuit.
I have UCD9224EVM board tool available. And I want to generate 15.26 Khz( The lower switching frequency, the better.)
The UCD9224 EVM board is with UCD7242 circuit. But the UCD7274 only can generate min 300Khz.(switch frequency) PWM signal.
It is too large that can not fit my request.
My question is
(1) If the UCD7274/7231…circuit is really needed? What should I do if I want to generate the 15.26 Khz PWM signal.
(2) If the UCD7274/7231 is not needed, and please advise me the circuit about how to generate 15.26Khz PWM signal.
