Is there possible to get PWM (0-5V) instead of (0-3.3V) in stm32f4?

I am trying to generate the PWM from STM32F4 micrcontroller. The PWM output was done but it is 0-3.3V range. May I possible to configure the PWM voltage range (0-5V) if so, can someone guide me the way to proceed it.

Thank you.  #stm32f4-pwm #pwm #stm324 #5v

Hi,

No this is not possible directly. You need to add a voltage level converterRob

If the PWM does not need to be fast, using a pullup to +5V with a 5-Volt tolarant output and the pin as open-drain could do.

May I know please , the sample code for open drain configuration?
