The A8499SLJ-T is a high voltage Step-Down Regulator that will handle a wide input operating voltage range. It requires an external clamping diode, inductor and filter capacitor and operates in both continuous and discontinuous modes. An internal blanking circuit is used to filter out transients resulting from the reverse recovery of the external clamp diode. To maintain voltage regulation during light load conditions, the switching regulator enters a cycle-skipping mode. An internal ramp generator and counter allow the output to slowly ramp up. To improve overall system efficiency, the regulator output, VOUT, is connected to the VBIAS input to supply the operating bias current during normal operating conditions. The ENB pin is externally pulled to ground to enable the device and begin the soft start sequence.
