I have got a PWM board from china that outputs at 5V but at 100 kHz, the voltage drops to about 2.82V. Hence I have implemented a mosfet driver to pull the amplitude ideally to be 10V to drive a mosfet that is part of a SMPS.
The mosfet driver that I was using was Microchip TC427CPA. I used a PSU of 12V while experimenting and the result was only about 5.5V output DC.
I tried adjusting the PSU to 17.5V and I've got an output of 8.28V DC. Based on the data sheet, it mentioned that output voltage should be Vdd - 0.025. I've grounded the other input interface and I've connected decoupling capacitance between Vdd and ground as per the datasheet.
Any advice to achieve the desired output?
I tried using Microchip TC4432EPA and while the PSU was set at 12V, I was able pull the output to 10.93V measured at pin 7 (Source Output). However I'm a bit confused with Pin 6 (Sink Output) and Pin 7 (Source Output) for which pin will be suitable to drive the N Channel Mosfet of my SMPS.
I am also unsure if the Microchip TC4432EPA is suited for SMPS applications as well. I hope someone can guide me along. Thanks in advance!
