(1/6) DC to DC Converters Distributed Power Supplies for Systems, Insulation Type Quarter Brick Type iQB/iQC Series Power supply systems for infrastructure devices used in communication networks primarily use brick-type DC to DC converters. As the voltage used for LSIs continues to drop, power supplies are expected to provide lower output, higher efficiencies, and lower noise levels. To meet these demands, we have developed quarter brick types that is smaller in size and produce low output voltage. FEATURES * Wide input voltage range (DC.36 to 75V or DC.18 to 36V) * There are 21 models in the lineup of products with low output voltages (1.2 to 5V). * High efficiency: 90%(3.3V and 5V output) * Heat sink is not required. * Remote ON-OFF function * Output voltage external variable function * Remote sensing function * Various protective functions * Two shapes: SMD and lead pin types * Low height power supplies (Height: 8.1mm) PRODUCT IDENTIFICATION iQB (1) 48 015A (2) (3) 018V (4) PART NUMBERS AND RATINGS (5) (1) Type name Quarter brick type iQB: Lead pin iQC: SMD (2) Rated input voltage (3) Output current (4) Output voltage (5) Option code iQB type 015: Standard(Negative on/off logic, Pin length: 5.08mm, Overvoltage protection shutdown type) 000: Positive on/off logic, Pin length: 3.68mm, Overvoltage protection automatic recovery type 001: Negative on/off logic, Pin length: 3.68mm, Overvoltage protection automatic recovery type 002: Positive on/off logic, Pin length: 2.79mm, Overvoltage protection automatic recovery type 003: Negative on/off logic, Pin length: 2.79mm, Overvoltage protection automatic recovery type 004: Positive on/off logic, Pin length: 5.08mm, Overvoltage protection automatic recovery type 005: Negative on/off logic, Pin length: 5.08mm, Overvoltage protection automatic recovery type 011: Negative on/off logic, Pin length: 3.68mm, Overvoltage protection shutdown type iQC type 001: Standard(Negative on/off logic) 000: Positive on/off logic Output voltage(V) Lead pin type 1.2 1.5 1.8 1.8 2.5 2.5 3.3 3.3 5 5 Supports 24V input 3.3 SMD type 1.2 1.5 1.8 1.8 2.5 2.5 3.3 3.3 5 5 Current(A) Part No. 25 25 15 25 10 20 10 20 8 15 iQB48025A012V iQB48025A015V iQB48015A018V iQB48025A018V iQB48010A025V iQB48020A025V iQB48010A033V iQB48020A033V iQB48008A050V iQB48015A050V 15 iQB24015A033V 25 25 15 25 10 20 10 20 8 15 iQC48025A012V iQC48025A015V iQC48015A018V iQC48025A018V iQC48010A025V iQC48020A025V iQC48010A033V iQC48020A033V iQC48008A050V iQC48015A050V * All specifications are subject to change without notice. 002-02 / 20040524 / ea33_br_iqbc.fm (2/6) SPECIFICATIONS AND STANDARDS Lead pin type SMD Rated output voltage and current1 Maximum output power W Input conditions Input voltage Edc V Input current A Inrush transient2 A 2S Efficiency % Output characteristics Output voltage Edc V Voltage adjustment range % Maximum output current A Minimum output current A Output voltage initial setting % Overvoltage protection V Overcurrent protection A Line regulation mV Load regulation mV Voltage Temperature stability mV regulation Dynamic response mV Ripple noise Ep-p mV Start up time ms Auxiliary functions Overvoltage protection Overcurrent protection Alarm output Over-temperature protection Remote ON-OFF Remote sensing Parallel operation Output voltage adjustment Master slave operation Standards Safety standards Constructions External dimensions mm Weight g Mounting method Oscillating method Oscillating frequency kHz Part No. iQB48025A012V iQC48025A012V 1.2V * 25A 30 iQB48025A015V iQC48025A015V 1.5V * 25A 37.5 36 to 75[Continuation]/100[Transient 4max. 4max. 0.2max. 0.2max. 78typ. 82typ. iQB48015A018V iQC48015A018V 1.8V * 15A 27 100ms] 4max. 0.2max. 85typ. iQB48025A018V iQC48025A018V 1.8V * 25A 45 iQB48010A025V iQC48010A025V 2.5V * 10A 25 iQB48020A025V iQC48020A025V 2.5V * 20A 50 4max. 0.2max. 84typ. 2max. 0.2max. 87typ. 4max. 0.2max. 86typ. 1.2 -10 to +10 25 2.5 1.5max. 1.4 to 1.8 35.0typ. 5max.(2typ.) 7max.(1typ.) 1.5 -10 to +10 25 2 2max. 1.7 to 2.3 35.0typ. 5max.(2typ.) 7max.(1typ.) 1.8 -10 to +10 15 1 1.6max. 2.15 to 2.58 22.5typ. 5max.(2typ.) 7max.(1typ.) 1.8 -10 to +10 25 1.8 1.6max. 2.15 to 2.58 35.0typ. 5max.(2typ.) 7max.(1typ.) 2.5 -10 to +10 10 0.75 1.6max. 2.7 to 3.5 14.0typ. 5max.(1typ.) 7max.(1typ.) 2.5 -10 to +10 20 1.5 1.6max. 2.7 to 3.5 26.0typ. 5max.(1typ.) 7max.(1typ.) 50max.(10typ.) 50max.(10typ.) 50max.(10typ.) 50max.(10typ.) 50max.(10typ.) 50max.(10typ.) 100max. 90typ. 100max. 90typ. 100max. 90typ. 220typ.[50 to 75%, sudden load change] 75max. 100max. 100max. 90typ. 90typ. 90typ.
