<Latch Protection Operation>
The operation of Latch protection circuit is as follows: When AMPOUT becomes "H" and the IC detects
maximum duty cycle, charge to an external capacitor, C2 of DELAY pin starts. The maximum duty cycle
continues and the voltage of DELAY pin reaches delay voltage detector threshold, VDLY, outputs "L" to EXT pin
and turns off the external power MOSFET.
To release the latch protection operation, make the supply voltage down to UVLO detector threshold or lower,
and make it rise up to the normal input voltage.
Once after becoming the maximum duty cycle, if the duty cycle decreases before latch operation works, the
charging the capacitor stops immediately, and the DELAY pin voltage is fixed at GND level with IDLY2.
The delay time of latch protection can be calculated with C2, VDLY, and the delay pin charge current, IDLY1, as in
the next formula.
