➀ Typical at TA = +25°C under nominal line voltage and balanced “full-load” conditions (5V @ 3.3A/3.3V @ 5A).
➁ Any combination of 5V/3.3V rated IOUT current, not to exceed 33 Watts of output power. (See derating graphs.)
➂ Ripple/Noise (R/N) measured over a 20MHz bandwidth. All models are specified with 1µF ceramic output capacitors.
➃ Tested from 10% load to 100% load (other output at 10% load).
➄ Nominal line voltage, no load/balanced full-power condition.
➅ Tested from no-load to 100% load (other output at no-load).
➆ Output trim may impact 5V load regulation.
