The L6986I is a device specifically designed for the isolated buck topology. Due to the P-Channel MOSFET as high-side power switch the device features 100% duty cycle operation. The primary output voltage can be accurately adjusted, whereas the isolated secondary output is derived by using a given transformer ratio. No optocoupler is required. The primary si.
