Notes: 1. Part number suffix “-AL” designates: - 36V to 53V Input voltage range - lower UVLO range (34V to 36V) - Autorecovery mode after fault protection 2. 20MHz BW limited with external 10uF tantalum cap. + 0.1uF ceramic cap across the output. 220uF low ESR cap required across the input pins. 3. Output may need to be derated and airflow added when operating at elvetaed ambient temperature. 4. All specifications are typical at nominal line, full load and 25oC ambient temp unless otherwise noted. 5. Technical Reference Notes should be consulted for detailed information when available. 6.
