Operation
Input and Output Impedance
The FPMR12TR7505*A 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
100µF) are recommended to minimize input ripple
voltage. The converter itself has on-board internal
input capacitance of 3µF with very low ESR (ceramic).

The FPMR12TR7505*A 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 placed in close proximity to the load
to improve transient performance and to decrease
output voltage ripple.

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.

ON/OFF (Pin 5)
The ON/OFF pin (pin 5) can be used to turn the
converter on or off remotely using a signal that is
referenced to GND (pin 3), as shown in Fig. A.
Two remote control options are available,
corresponding to negative and positive logic. In the
negative logic option, to turn the converter on Pin 5
should be at logic low or left open, and to turn the
converter off Pin 5 should be at logic high or connected
to Vin. In the positive logic option, to turn the converter
on Pin 5 should be at logic high, connected to Vin or left
open, and to turn the converter off Pin 5 should be at
logic low.

Pin 5 is internally pulled-down. A TTL or CMOS logic
gate, or an open collector/drain transistor can be
used to drive Pin 5. When using an open collector/

be connected to Vin (See Fig.A).
The device driving Pin 5 must be capable of:
(a) Sinking up to 0.2mA at low logic level (≦0.8V)

Protection Features
Input Under-Voltage Lockout
From a turned-on state, the converter will turn off
automatically when the input voltage drops below
typically 4.4V. It will then turn on automatically when
the input voltage reaches typically 5.5V.

Output Over-Current Protection (OCP)
The converter is self-protected against over-current
and short circuit conditions. On the occurrence of an
over-current condition, the converter will enter a pulse-
by-pulse hiccup mode. On the removal of the over-
current or short circuit condition, Vout will return to the

The converter meets North American and International

conditions in that the output voltages are ELV (extra-

that the converter is not internally fused: to meet

Characterization
Overview
The converter has been characterized for several
operational features, including thermal derating
(maximum available load current as a function of
ambient temperature and airflow), efficiency, power
dissipation, start-up and shutdown characteristics,
ripple and noise, and transient response to load step-
changes.

It is advisable to check the converter temperature in
the actual application, particularly if the application
calls for loads close to the maximums specified by
the derating curves. IR thermography or
thermocouples may be used for this purpose. In the
latter case, AWG#40 gauge thermocouples are
recommended to minimize interference and
measurement error. An optimum location for
placement of a thermocouple is indicated in Fig. C.

Thermal Derating
Figs *V-1 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(50 LFM) to 400 LFM (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 5.

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 (5A)
A maximum component temperature of 120°C should
not be exceeded in order to operate within the
derating curves. Thus, the temperature at the
thermocouple location shown in Fig. C should not
exceed 120°C in normal operation.

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.

FDK’s custom wind tunnel was used to provide
precise horizontal laminar airflow in the range of 50
LFM (equivalent to natural convection, NC) to
400LFM, at ambient temperatures between 30°C and
85°C. Infrared (IR) thermography and thermocouples
were used for temperature measurements.

Ripple and Noise
The test circuit setup shown in Fig D was used to
obtain the output voltage ripple. And Fig. E was used
to obtain the input reflected ripple current waveforms.
The output voltage ripple waveform was measured
across a 1µF ceramic capacitor. at full load current.
