Dear, Sir.
My customer is designing to realize PWM dimming by external NMOS FET utilizing
COFF pin as below;
1)MCU generates PWM signal.
2)PWM siganl is provided to COFF pin though RC and NMOS FET gate driver.
The datasheet recommends to utilize EN pin with Cext & Rext which avoid the unwanted max off-time
condition.
Is it a suitable solution as other PWM dimming by external NMOS FET?
Best Regards,
H. Sakai
