The addition of a 33uF electrolytic capacitor with an ESR < 1Ω and 2.2uF ceramic capacitor across the input will help to ensure stability of the power module in many applications. To cover applications where decoupling capacitance is needed at the load, the power module has been designed to exhibit stable operation with external load capacitance up to 2200uF. In case using electrolytic capacitors at input and/or output, must be careful for aging degradation of electrolytic capacitors. 入力、及び出力ﾗｲﾝのｲﾝﾀﾞｸﾀﾝｽはFPER48T01238*A* の安定動作に 大きな影響があります。 多くのｱﾌﾟﾘｹｰｼｮﾝで入力ﾗｲﾝにESRが1Ω未満 の33uF電解ｺﾝﾃﾞﾝｻと2.2uFのｾﾗﾐｯｸｺﾝﾃﾞﾝｻを付けることでﾊﾟﾜｰﾓｼﾞｭｰﾙ の安定動作が可能です。 負荷端にﾃﾞｶｯﾌﾟﾘﾝｸﾞｺﾝﾃﾞﾝｻが付くｱﾌﾟﾘｹｰｼｮ ﾝでは、2200uFまで安定して動作するよう設計されています。 入力、及 び出力ﾗｲﾝに電解ｺﾝﾃﾞﾝｻを使用する場合は、電解ｺﾝﾃﾞﾝｻの経年劣化 にご注意ください。 In the negative logic version the power module turns on when the ON/OFF pin is at logic low and turns off when it is at logic high (open). If the ON/OFF pin is connected directly (shorted) to Vin(-), the power module will turn on without the need for a control signal. ﾈｶﾞﾃｨﾌﾞﾛｼﾞｯｸはON/OFFﾋﾟﾝが論理的にLowで動作し、論理的にHigh (open)で停止します。 ON/OFFﾋﾟﾝがVin(-)に接続されている場合、ｺﾝﾄ ﾛｰﾙ信号が無くてもﾊﾟﾜｰﾓｼﾞｭｰﾙはONします。 The ON/OFF pin is pulled up internally. A mechanical switch, open-collector transistor, or FET can be used to drive the ON/OFF pin. The device must be capable of sinking up to 0.2mA at a voltage ≦ 0.8V. An external voltage source (+20V maximum), capable of sourcing or sinking up to 1mA depending on the polarity, can also be used to drive the ON/OFF pin. ON/OFFﾋﾟﾝはﾓｼﾞｭｰﾙ内部でﾌﾟﾙｱｯﾌﾟされています。ON/OFFﾋﾟﾝを駆動 するために機械的ｽｲｯﾁ、ｵｰﾌﾟﾝｺﾚｸﾀｰﾄﾗﾝｼﾞｽﾀ、又はFETを使用可能 です。 使用する部品は0.8V以下の電圧で0.2mAまで電流を流せる必要 があります。 1mAまで流せる外部電源(最大+20V)がON/OFFﾋﾟﾝを駆 動するのに使用可能です。 To minimize output ripple voltage and to ensure stability of the power module, the addition of external load capacitor with low ESR is required. These capacitors should be placed in close proximity to the load to improve transient performance and to decrease output voltage ripple. 出力ﾘｯﾌﾟﾙを最小にし、ﾊﾟﾜｰﾓｼﾞｭｰﾙの安定性を確実にするため、低 ESRの出力ｺﾝﾃﾞﾝｻを付けて下さい。 過渡時の特性向上と出力ﾘｯﾌﾟﾙ 低減のために負荷の近傍にこれらのｺﾝﾃﾞﾝｻを実装することをお勧めし ます。 ON/OFF Converter Vin－ Fig A: A typical configuration for remote ON/OFF ON/OFF (Pin 2) The ON/OFF pin (Pin 2) can be used to turn the power module on or off remotely using a signal that is referenced to Vin(-) (Pin 3). Two remote control options are available, corresponding to positive and negative logic. A typical configuration for remote ON/OFF is shown in Fig. A. ON/OFF端子(2番ﾋﾟﾝ)はVin-(3番ﾋﾟﾝ)を基準としたﾘﾓｰﾄ信号によりﾊﾟﾜｰ ﾓｼﾞｭｰﾙをON/OFFするのに使用できます。 ﾘﾓｰﾄｺﾝﾄﾛｰﾙはﾎﾟｼﾞﾃｨﾌﾞと ﾈｶﾞﾃｨﾌﾞの2種類が可能です。 一般的なﾘﾓｰﾄON/OFF回路を図Aに示 します。 In the positive logic version the power module turns on when the ON/OFF pin is at logic high (open) and turns off when it is at logic low. When the ON/OFF pin is left open, the power module is on. Voltage ranges for logic high/low are provided in the Electrical Specifications section. ﾎﾟｼﾞﾃｨﾌﾞﾛｼﾞｯｸはON/OFFﾋﾟﾝが論理的にHigh (open)で動作し、論理的 にLowで停止します。 ON/OFFﾋﾟﾝが未接続 (ｵｰﾌﾟﾝ)の場合、ﾊﾟﾜｰﾓ Http://www.fdk.com Page 4 of 17 Ver. 2.0 Jan. 12, 2018 Delivering Next Generation Technology Series Data Sheet FPER48T01238*** 36-75Vdc Input, 37.5A, 12Vdc Output Remote Sense (Pins 5 and 7) To compensate for voltage drops that occur between the output pins of the power module and the point of regulation (typically, the load), the SENSE(-) (Pin 5) and SENSE(+) (Pin 7) pins should be connected across the load or at the point where regulation is needed (see Fig. B). ﾊﾟﾜｰﾓｼﾞｭｰﾙの出力端子と電圧制御が必要なﾎﾟｲﾝﾄ(通常負荷端)との 間で発生する電圧降下を補正するためには、SENSE(-) (Pin 5) と SENSE(+) (Pin 7) を負荷側か、又は電圧精度が必要なﾎﾟｲﾝﾄに接続し ます｡ (図B参照) Vin(+) Vin FPER Series Power Module Vout(+) Note that the remote sense function will allow the voltage across the output pins to be higher than the nominal output voltage, in order to maintain regulation at the load. The system design should take this into account to ensure that the power drawn from the power module under a given set of conditions does not exceed the maximum output power of the power module. For any given ambient conditions, the maximum output power of the power module is the product of the maximum output current, as defined by the derating curves, and the nominal output voltage. ﾘﾓｰﾄｾﾝｽ機能は負荷端での電圧を制御するため、出力端の電圧を通 常よりも高くします。 ｼｽﾃﾑの設計では本件に留意し、ﾊﾟﾜｰﾓｼﾞｭｰﾙの 出力電力が最大定格電力を超えないように注意してください。 いずれ の外部条件においてもﾊﾟﾜｰﾓｼﾞｭｰﾙの最大定格電力はﾃﾞｨﾚｰﾃｨﾝｸﾞｶｰ ﾌﾞに記載された最大出力電流と出力電圧で規定されます。 SENSE(+) TRIM Rload SENSE (-) Vin(-) Vout(-) Fig. B: Circuit configuration for remote sense If remote sensing is not necessary, the SENSE(-) pin should be connected to the Vout(-) pin (Pin 4), and the SENSE(+) pin should be connected to the Vout(+) pin (Pin 8) to ensure proper regulation of the power module output voltage. If the SENSE pins are left open, the power module will regulate at an output voltage that is slightly higher than specified. ﾘﾓｰﾄｾﾝｽが必要でないなら、SENSE(-)ﾋﾟﾝはVout(-) (4番ﾋﾟﾝ) と、 SENSE(+)ﾋﾟﾝはVout(+) (8番ﾋﾟﾝ) に接続し､出力電圧の電圧精度を確実 にします｡ SENSEﾋﾟﾝが接続されていないと出力電圧は規定の値よりわ ずかに上昇します｡ To minimize noise pick-up, traces from the SENSE pins to the load should be located in proximity to a ground plane. If wiring discretely, a twisted pair is recommended. ﾉｲｽﾞの影響を最小に抑えるため、ｾﾝｽﾋﾟﾝから負荷への配線はｸﾞﾗﾝﾄﾞ配 線に近くしてください。 もし線材で直接配線する場合は、ﾂｲｽﾄﾍﾟｱ線の 使用をお勧めします。 Note that the output over-voltage protection (OVP) feature of the power module depends on the voltage across the Vout(+) and Vout(-) pins, and not across the SENSE pins. To preclude unnecessary triggering of the OVP feature, the resistance (and thus voltage drop) between the output pins of the power module and the load should be kept at a minimum. このﾊﾟﾜｰﾓｼﾞｭｰﾙの出力電圧保護(OVP)はVout(+)とVout(-)間の電圧に 依存し、ｾﾝｽﾋﾟﾝ間の電圧には依存しません。 OVPの予期せぬﾄﾘｶﾞを 防ぐために、ﾊﾟﾜｰﾓｼﾞｭｰﾙの出力端子と負荷間の抵抗成分(電圧ﾄﾞﾛｯﾌﾟ) は最小にしてください｡ Http://www.fdk.com Page 5 of 17 Ver. 2.0 Jan. 12, 2018 Delivering Next Generation Technology Series Data Sheet FPER48T01238*** 36-75Vdc Input, 37.5A, 12Vdc Output Output Voltage Adjust/TRIM (Pin 6) The output voltage can be trimmed up 10% or down 50% relative to the nominal output voltage using an external resistor. 出力電圧は外部抵抗を接続する事で､定格電圧に対し +10%､-50%の調 整が可能です｡ The TRIM pin should be left open if trimming is not being used.

On the occurrence of an over-current condition, the power module will reduce the output voltage until it shuts down. Once the power module has shut down, it will attempt to restart about every 200ms until the over-current or short circuit condition is removed. Note that the power module is not internally fused: to meet safety requirements, a fast acting in-line fuse with a maximum rating in the table below must be used in the positive input line. このﾊﾟﾜｰﾓｼﾞｭｰﾙは内部にﾋｭｰｽﾞを持っていませんので、安全規格に適 合させるためには、入力ﾗｲﾝのﾌﾟﾗｽ側に即断型で最大定格下表のﾋｭｰ ｽﾞを接続してください。 このﾊﾟﾜｰﾓｼﾞｭｰﾙは過電流と負荷短絡に対し自己保護します｡ 過電流 状態になると､ﾊﾟﾜｰﾓｼﾞｭｰﾙはｼｬｯﾄﾀﾞｳﾝするまで出力電圧を低下させま す｡ ﾊﾟﾜｰﾓｼﾞｭｰﾙがｼｬｯﾄﾀﾞｳﾝ後、OCP状態、又は負荷短絡が解除され るまで およそ200ms毎に再起動を繰り返します｡ Output Voltage 12V Fuse Rating 20A Output Over-Voltage Protection (OVP) The power module provides protection against overvoltage conditions at the output.

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. Optimum locations for placement of thermocouples are indicated in Fig. G. ﾊﾟﾜｰﾓｼﾞｭｰﾙの温度を実際の使用環境で測定することをお勧めします。 特に実使用上の負荷が温度ﾃﾞｨﾚｰﾃｨﾝｸﾞの最大値に近い場合は測定 が必要です。温度測定には赤外線ｻｰﾓｸﾞﾗﾌｨ、又は熱電対をお使いい ただけます。熱電対を使用する場合、風の妨げになることを防ぐため と、測定誤差を少なくするため、AWG40の熱電対を推奨します。熱電対 での測定に最適な位置を図Gに表します。 Test Conditions To ensure measurement accuracy and reproducibility, all thermal and efficiency data were taken with the power module soldered to a standardized thermal test board. The thermal test board was mounted inside FDK’s custom wind tunnel to enable precise control of ambient temperature and airflow conditions. 測定精度、及び再現性を確実にするために、全ての温度、及び効率 ﾃﾞｰﾀは標準化された温度評価ﾎﾞｰﾄﾞにﾊﾟﾜｰﾓｼﾞｭｰﾙを半田付けして取 得しています。温度評価ﾎﾞｰﾄﾞをFDK特製の風洞実験設備内に設置す ることで、環境温度、及び風量を精密に管理しています。 Fig. E: FDK Original Wind Tunnel 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 power module 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 power module to the PCB, thereby providing a worst-case but consistent set of conditions for thermal measurements. 温度評価ﾎﾞｰﾄﾞは厚さ0.060”(1.6mm)厚の4層PCBで作成しています。表 面2層の銅箔はﾊﾟﾜｰﾓｼﾞｭｰﾙを実装するためのﾊﾟｯﾄﾞと周辺部品へのﾊﾟ ﾀｰﾝのみに限定しています。内側2層は70μmの銅箔で電力、及びｸﾞﾗﾝ ﾄﾞﾗｲﾝを形成しています。このように表層の銅箔を限りなく少なくした温 度評価ﾎﾞｰﾄﾞは、ﾊﾟﾜｰﾓｼﾞｭｰﾙからPCBへの熱の逃げを制限し、ﾜｰｽﾄ ｹｰｽでありながら矛盾の無い温度評価条件を実現しています。 Fig. F: Test Chamber FDK’s custom wind tunnel was used to provide precise horizontal laminar airflow in the range of 50 LFM to 600LFM, at ambient temperatures between 30°C and 85°C. Infrared (IR) thermography and thermocouples were used for temperature measurements.
