Description
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 sink capability up to 1.9 A (even during softstart)
allows a proper energy transfer to the secondary side as well as enables a
tracked soft-start of the secondary output. The control loop is based on a peak
current mode architecture and the device operates in forced PWM. The 300 ns
blanking time filters oscillations, generated by the transformer leakage inductance,
making the solution more robust. Pulse by pulse current sensing on both power
elements implements an effective constant current protection in the primary side.
Due to the primary reverse current limit, the secondary output is protected against
short circuit events. A primary output voltage supervisor, which notifies primary output
voltage regulation through the RST open collector output, overvoltage protection,
adjustable switching frequency, synchronization and a programmable soft-start are
also available.
