Unipolar Wide Input
 These are partial model numbers. Please refer to the full model number structure for complete
ordering part numbers.
 Sense input is not included for 12 V
OUT and higher models. Sense is optional for 5 VOUT and lower.
 All specifi cations are typical at nominal line voltage and full load, +25 deg.C. unless otherwise
noted. See detailed specifi cations.
 Output capacitors are 1 μF ceramic || 10 μF electrolytic. Input cap is 22 μF, low ESR.
 I/O caps are necessary for our test equipment and may not be needed for your application.
