HPQ-3.3/50-D48 Series
Isolated High Power Quarter Brick DC-DC Converters
Speci?cation Notes
(1) All models are tested and speci?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-
ment and may not be required to achieve speci?ed performance in your applications. All models are stable and regulate within spec under no-load conditions.
All speci?cations are typical unless noted. General conditions for Speci?cations are +25 °C, Vin=nominal, Vout=nominal, full load. Adequate air?ow must be supplied for extended testing under power.
(2) Re?ected Input Ripple Current is tested and speci?ed over a 5 Hz to 20 MHz bandwidth. Input ?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 air?ow, the DC-DC converter will tolerate brief full current outputs if the
total RMS current over time does not exceed the Derating curve. All Derating curves are presented at sea level altitude. Be aware of reduced power dissipation with increasing density altitude.
(4) Mean Time Before Failure is calculated using the Telcordia (Belcore) SR-332 Method 1, Case 3, ground ?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
referenced to Input Common.
(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 ?lter. See I/O Filtering and Noise Reduction.
(9) All models are fully operational and meet published speci?cations, including “cold start” at –40 °C. Maximum power requires that the package temperature of all on-board components must never exceed
+128°C.
(10) Regulation speci?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 speci?ed with the Input/Output ?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-
sient response. Use only as much output ?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.
(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.
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.
(13) Do not exceed maximum power speci?cations when adjusting the output trim.
(14) At zero output current, the output may contain low frequency components which exceed the ripple speci?cation. The output may be operated inde?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-?lm resistors.
(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.
