The chip's advanced protection features include short-circuit protection and current and temperature limits. During a sustained over-current event, the IC shuts down and restarts after a delay to reduce average power dissipation into a fault. During start-up, the IC controls the output slew rate to minimize input current and output overshoot at the end of softstart. The IC maintains a consistent soft-start ramp, regardless of output load during start-up. The FAN5355 is available in 10-lead MLP (3x3mm) and 12-bump CSP packages.
