FPDK12SR8003PSV
5.6-14.0Vdc Input, 3A, 0.8-6.6Vdc Output
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 (3A)
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
は
(ii) ｺﾝﾊﾞｰﾀの公称定格電流 (3A)
Note that continuous operation beyond the derated
current as specified by the derating curves (Fig.1)
may lead to degradation in performance and
reliability of the converter and may result in
permanent damage.
出力電流ﾃﾞｨﾚｰﾃｨﾝｸﾞｶｰﾌﾞ(図1)で指定された定格電流を超えた連続し
た操作は、性能の低下、信頼性の低下、及びﾓｼﾞｭｰﾙの破損を引き起こ
すことがあります。
The main heat dissipation method of this converter is
to transfer its heat to the system board. Thus, if the
temperature of the system board goes high, even
with the low ambient temperature, it may exceed the
guaranteed temperature of components.
このｺﾝﾊﾞｰﾀの主な放熱方法は、ｼｽﾃﾑ基板へ自身の熱を逃がすという
ものです。このため、周囲温度が低くてもｼｽﾃﾑ基板の温度が高温にな
ると、使用部品の保証温度を超えることがあります。

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.
