(1) All models are tested and specifi ed with external 1||10 μF output capacitors and no external input capacitor. All capacitors are low ESR types. These capacitors are necessary to accommodate our test equip-
(2) Refl ected Input Ripple Current is tested and specifi ed over a 5 Hz to 20 MHz bandwidth. Input fi ltering is Cin=33 μF, 100V, Cbus=220 μF, 100V electrolytic, Lbus=12 μH.
(3) Note that Maximum Power Derating curves indicate an average current at nominal input voltage. At higher temperatures and/or lower airfl ow, the DC/DC converter will tolerate brief full current outputs if the
(4) Mean Time Before Failure is calculated using the Telcordia (Belcore) SR-332 Method 1, Case 3, ground fi xed conditions, Tpcboard=+25 °C, full output load, natural air convection.
(5) The On/Off Control is normally controlled by a switch, relay or open collector or open drain transistor. But it may also be driven with external logic or by applying appropriate external voltages which are
(6) Short circuit shutdown begins when the output voltage degrades approximately 2% from the selected setting.
(7) The output is not intended to sink appreciable reverse current. This may damage the outputs.
(8) Output noise may be further reduced by adding an external fi lter. See I/O Filtering and Noise Reduction.
(9) All models are fully operational and meet published specifi cations, including “cold start” at –40 °C. Maximum power requires that the package temperature of all on-board components must never exceed
(10) Regulation specifi cations describe the deviation as the line input voltage or output load current is varied from a nominal midpoint value to either extreme.
(11) The converter is normally specifi ed with the Input/Output fi ltering listed in Note 1. Higher capacitive load will reduce noise but at the expense of delayed settling time, extended turn-on time and slower tran-
(12) “Hiccup” overcurrent operation repeatedly attempts to restart the converter with a brief, full-current output. If the overcurrent condition still exists, the restart current will be removed and then tried again.
(13) Do not exceed maximum power specifi cations when adjusting the output trim.
(14) At zero output current, the output may contain low frequency components which exceed the ripple specifi cation. The output may be operated indefi nitely with no load.
(15) Input Fusing: To ensure reverse input protection, always connect an external input fast-blow fuse in series with the +Vin input.
(16) Output accuracy is dependent on user-supplied trim resistors. To achieve high accuracy, use ±1% or better tolerance metal-fi lm resistors.
Soldering Guidelines
Murata Power Solutions recommends the specifi cations below when installing these converters. These specifi cations vary depending on the solder type. Exceeding these specifi ca-
tions may cause damage to the product. Your production environment may differ; therefore please thoroughly review these guidelines with your process engineers.
Absolute maximums are stress ratings. Exposure of devices to greater than any of these conditions may adversely affect long-term reliability. Proper operation under conditions other than those listed in the
(17.) Always connect the sense pins. If they are not connected to a remote load, wire each sense pin to its respective voltage output at the converter pins.

ment and may not be required to achieve specifi ed performance in your applications. All models are stable and regulate within spec under no-load conditions.
All specifi cations are typical unless noted. General conditions for Specifi cations are +25 °C, Vin=nominal, Vout=nominal, full load. Adequate airfl ow must be supplied for extended testing under power.

sient response. Use only as much output fi ltering as needed and no more. Thoroughly test your system under full load with all components installed. Low ESR capacitors with high capacitance may degrade
dynamic performance.
This short current repeating pulse prevents overheating and damaging the converter. Output current limit and short circuit protection is non-latching. Once the fault is removed, the converter immediately
recovers normal operation.
