APW7066
General Description (Cont.)
the external clock. The possible synchronous frequency
is from 150kHz to 800kHz. There is no Rds(on)
sensing or under-voltage sensing on APW7066.
However, it provides a simple short-circuit protection
by monitoring the COMP1 and COMP2 for over-voltage.
When any of two pins exceeds their trip point and the
condition persists for 1-2 internal clock cycle (3-6us
at 300kHz), then it will shut down all regulators.
