Synchronous Mode

When the MODE / SYNC pin is connected to a clock, chip’s SW outputs will be synchronized to it

automatically. The synchronous range is from 0.5~1.5 time input clock frequency. In this mode,

pulse skip mode is selected automatically.

Over Current Protection

FP6166 limits the peak main switch current cycle by cycle. When over current happens, chip will

turn off the main switch and turn the synchronous switch on until next cycle.

Short Circuit Protection

When the FB pin drops below 300mV, the chip will tri-state the output pin SW automatically. After

300us rest to avoid over heating, chip will re-initiate PWM operation with soft start.

Thermal Protection

FP6166 will shutdown automatically when the internal junction temperature reaches 150°C to

protect both the part and the system.
