Static Performance

International

Efficiency

Efficiency is required to be at least 80% at

full load. Thanks to the very efficient 20V

low V

MOSFETs, IRVRM2 exceeds the

required specification by a comfortable

margin.

Maximum Junction Temperature

Analysis of Q1 junction temperature shows

that it remains within specifications at an

ambient temperature of 50°C, even in still air.

Dynamic Performance

Fig 18. Transient Load Current Fall time

Transient Load Test Conditions

The Intel specification requires the supply to

stay within its ±5% specification during

transient load event of 0.8A-to-12.7A at a rate

of 30A/µs. Although most motherboards do

not require this full level of performance,

IRVRM2 meets the full transient response

specification.

Load Regulation

The output must stay within its -2.1% ~ +3.6%

static specification from no load to full load.

Fig 16. Typical Line Regulation

Line Regulation

The Intel specification requires the line

voltage to be within ±5% of nominal voltage.

IRVRM2 easily meets line regulation

specification even up to ±10%.
