NOTES:
1 VIN=Enable, 5mV≤(sense high-sense low)≤75mV, IL=0A, COUT=6x330µF, CIN=6x220µF, CTON=0.01µF unless otherwise specified.
2 This parameter is guaranteed by design but need not be tested. Typical parameters are representative of actual device performance but are for reference only.
3 All output parameters are tested using a low duty cycle pulse to maintain TJ = TC.
4 Industrial grade and 'E' suffix devices shall be tested to subgroup 1 unless otherwise specified.
5 Military grade devices ('H' suffix) shall be 100% tested to subgroups 1,2 and 3.
6 Subgroup 1
TA=TC=+25°C
Subgroup 2
TA=TC=+125°C
Subgroup 3
TA=TC=-55°C
7 Actual switching frequency can be load dependent if output current is low. Refer to typical performance curves.
8 Alternate output voltages are available. Please contact the factory.
9 Continuous operation at or above absolute maximum ratings may adversely effect the device performance and/or life cycle.
