Thermal Derating
Fig.1 to Fig.4 show the maximum available load
current vs. ambient temperature and airflow rates.
Ambient temperature was varied between 30°C and
85°C, with airflow rates from NC(50LFM) to 400LFM
(0.25m/s to 2.0m/s). The converter was mounted
horizontally, and the airflow was parallel to the long
axis of the converter, going from pin 1 to
pin 8.

ﾊﾞｰﾀの長手方向に平行で1番ﾋﾟﾝから8番ﾋﾟﾝに向けて吹いています。
The maximum available load current, for any given
set of conditions, is defined as the lower of:
(i) The output current at which the temperature of any
component reaches 120°C, or
(ii) The current rating of the converter (6A)
各々の測定条件で最大出力電流の値は下記のとおり定義します。
(i) いずれかの部品の温度が120℃に到達した時点の出力電流値、又

(ii) ｺﾝﾊﾞｰﾀの公称定格電流 (6A)
Note that continuous operation beyond the derated
current as specified by the derating curves
(Fig.1 to Fig.4) may lead to degradation in
performance and reliability of the converter and may
result in permanent damage.

Test Circuit
The test circuit setup shown in Fig. F was used to
obtain the output voltage ripple and output voltage
response to step load change. Fig. G was used to
obtain the input reflected ripple current waveforms.
