OUTPUT
parameter conditions/description min typ max units
line regulation full load, input voltage from low to high ±0.2 ±0.5 %
load regulation 5% to 100% load ±0.4 ±0.75 %
voltage accuracy 5% to 100% load ±1 ±3 %
no-load voltage accuracy input voltage range ±1.5 ±5 %
voltage balance
3
dual output, balanced loads ±0.3 ±0.5 %
switching frequency 100% load, nominal input voltage, PFM mode 200 KHz
transient recovery time 25% load step change 0.5 2 ms
transient response deviation 25% load step change ±2.5 ±5 %
temperature coeffecient 100% load ±0.02 ±0.03 %/°C
Notes: 3. For dual output models, unbalanced loads should not exceed ±5%. If ±5% is exceeded, it may not meet all specications.
