SS clamp
The SS clamp circuit limits the signal level on error-amplifier output during start-up. The voltage on SS is
amplified and used to override the error-amplifier output until it rises above that output, at which point the error
amplifier takes over. This prevents the input to the PWM comparator from exceeding its common-mode range
(i.e., error amplifier output too high to be reached by the current ramp) by limiting the maximum voltage on the
error-amplifier output during start-up.
Soft start causes the output voltage to increase to the regulation point at the controlled rate. The voltage on the
charging soft-start capacitor gradually raises the clamp on the error amplifier output voltage, limiting surge
currents at power up by increasing the current limit threshold on a cycle-by-cycle basis. A soft-start cycle is
initiated when either the enable (EN) signal is switched high or an overcurrent fault condition triggers the
discharge of the soft-start capacitor.
undervoltage lockout (UVLO)
The supply voltage is fed through a voltage divider to the input of the UVLO and compared to a reference. The
undervoltage-lockout logic prevents the MOSFET from turning on while the supply voltage is below the
undervoltage-lockout voltage threshold, and once the supply voltage on V CC is above the threshold, an SS cycle
is initiated.
