NOTES:
(1) Low duty cycle pulse testing with Kelvin connections required.
(2) Minimum input to output voltage differential required to maintain 1% regulation.
(3) Current used to drive the output section.
(4) Required to maintain regulation. Resistor divider R1, R2 is usually utilized for minimum load current.
(5) VRIPPLE = 1VPK-PK, 120Hz.
(6) 30ms.
(7) IRATED = 1.5A for EZ1583, 3A for EZ1582, 5A for EZ1581 and 7A for EZ1580.
