The ATtiny85 datasheet says that pins 2 and 3 can be used as PWM outputs OC1B and OC1B# - same signal source, just negated. Can I leverage this to form a synchronous-rectifying switch-mode power supply with a pair of complementary power MOSFETs (the two MOSFETs inside AO4606) for a more efficient design?
Also how to use the internal 1.1V reference and the AIN1 input to form the feedback loop? I don't want to give up RESET or hog up the I2C lines so this is the only pin remained.
