Note 1 INT Interrupt is an Open-Drain output. Logic high level becomes asserted within TINT(HIGH) when an over-current condition

has been detected. After the over-current event no longer persist the INT becomes de-asserted after TINT(LOW).

Note 2 CCM - Continuous Conduction Mode Indicator Output. CCM is an Open-Drain digital output that becomes Low when

the load is high and the converter switches to the continuous conduction mode (CCM). The CCM output continues to toggle

when the converter is in non-CCM mode. Customers might use LP filter to convert the toggling signal to a DC signal, and based

on DC level to identify the converter operation mode.
