CURRENT LIMIT
Sufficient margin shall be kept between normal Pin1 level and the latchoff point in order to avoid false triggering.
Ramp Compensation
Ramp compensation is a known mean to cure
subharmonic oscillations. These oscillations take place at
half the switching frequency and occur only during
Continuous Conduction Mode (CCM) with a dutycycle
greater than 50%. To lower the current loop gain, one usually
injects between 50 and 100% of the inductor downslope.
Figure 22 depicts how internally the ramp is generated.
