Soft-start circuit generates a ramp by charging an external capacitor with a 13uA constant current
source. This current source can start to charge the external soft start capacitor only when POR of IC
and DVD reach their threshold and VIDs are set. The pulse width of PWM signal and V CORE are clamped
by rising ramp to reduce the inrush current and the stress on the power devices.
Over-current protection trip point is able to be programmed by an external resistor. OCP is triggered if
one of the channels reaches this set current which is 1.6V / 0.5R IMAX . Controller forces PWM output
latched at high impedance to turn off both control and Sync FETs in the power stage and initial the
hiccup mode protection. The SS pin voltage is pulled low with a 13uA current after it is less than 90%
VCC. The converter restarts after SS pin voltage is lower than 0.2V. Three times of OCP disable the
converter and only release the latch by POR acts.
This is over current protection during operation
This is over current protection during startup
