FPDK05SR8006PSV
3.0-5.5Vdc Input, 6A, 0.8-3.465Vdc Output
Operation
Input and Output Impedance
The FPDK05SR8006PSV converter should be
connected to a DC power source using a low
impedance input line. In order to counteract the
possible effect of input line inductance on the stability
of the converter, the use of decoupling capacitors
placed in close proximity to the converter input pins is
recommended. This will ensure stability of the
converter and reduce input ripple voltage. Although
low ESR Tantalum or other capacitors should
typically be adequate, very low ESR capacitors
(ceramic, over 94μF) are recommended to minimize
input ripple voltage. The converter itself has on-board
internal input capacitance of 6uF with very low ESR
(ceramic).
FPDK05SR8006PSVと入力電源間は低ｲﾝﾋﾟｰﾀﾞﾝｽで接続してください。
ｺﾝﾊﾞｰﾀの安定性に影響のある入力ｲﾝﾀﾞｸﾀﾝｽを抑えるため、ｺﾝﾊﾞｰﾀの
入力ﾋﾟﾝの近傍にﾃﾞｶｯﾌﾟﾘﾝｸﾞｺﾝﾃﾞﾝｻを付加することをお勧めします。こ
れによりｺﾝﾊﾞｰﾀの安定動作を確実にし、入力ﾘｯﾌﾟﾙ電圧を抑制します。
低ESRﾀﾝﾀﾙ、又はその他のｺﾝﾃﾞﾝｻも一般的には問題ありませんが、
入力ﾘｯﾌﾟﾙを最小にするためには、非常に低ESRｺﾝﾃﾞﾝｻ(ｾﾗﾐｯｸで94μ
F以上)を推奨します。ｺﾝﾊﾞｰﾀ自身は入力回路に極低ESRの6uFｾﾗﾐｯｸ
入力ｺﾝﾃﾞﾝｻを搭載しています。
The FPDK05SR8006PSV turns on when the
REMOTE pin is at logic high (open) and turns off
when it is at logic low. When the REMOTE pin is left
open, the converter is on. Voltage ranges for logic
high/low are provided in the Electrical Specifications
section.

An open collector (open -drain) transistor can be

REMOTE
Control signal
The FPDK05SR8006PSV is capable of stable
operation with no external capacitance on the output.
To minimize output ripple voltage, the use of very low
ESR ceramic capacitors is recommended. These
capacitors should be placed in close proximity to the
load to improve transient performance and to
decrease output voltage ripple.
FPDK05SR8006PSVは出力に外付けｺﾝﾃﾞﾝｻが無い状態でも安定して

Note that the converter does not have a SENSE pin
to counteract voltage drops between the output pins
and the load. The impedance of the line from the
converter output to the load should thus be kept as
low as possible to maintain good load regulation.

Note that the tolerance of a trim resistor will affect the

a tighter tolerance can be obtained by using two

resistor.

The converter has been characterized for several

ambient temperature and airflow), efficiency, power

ripple and noise, and transient response to load

taken with the converter soldered to a standardized

precise control of ambient temperature and airflow

The thermal test board comprised a four layer printed
circuit board (PCB) with a total thickness of 0.060”.
Copper metallization on the two outer layers was
limited to pads and traces needed for soldering the
converter and peripheral components to the board.
The two inner layers comprised power and ground
planes of 2 oz. copper. This thermal test board, with
the paucity of copper on the outer surfaces, limits
heat transfer from the converter to the PCB, thereby
providing a worst-case but consistent set of
conditions for thermal measurements.

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.
