(1) Unless otherwise noted, specifications are identical for all options.
(2) Forced current Share not available for 3.3V Models.
(3) Derates same as Output Power.
(4) Current Limit is rectangular. After the overload is removed, output is
automatically restored.
(5) See power derating curve, Figure 4.
(6) Ripple and noise will be approximately 1.5 times higher when
operating temperature range is between –10°C to 0°C.
(7) 0-71°C, 0-100% load.
(8) Sense resistor on C and Y Models used for current
monitoring. See “Current Monitor.” on page 2 for details.
