I am implementing a system where I need to use 2 switches, 1 NMOS and another PMOS. The switches are controlled by a PWM wave that operates at a frequency of 1MHz. You can see in the attached figure the current that is needed at each gate. The NMOS transistor is not critical and does not require a drive, but in the case of PMOS there is a need for a gate driver but I am not able to find any that consume little (max 2 / 3mW).enter image description here Thank you!
