(1/4) DC to DC Converters Distributed Power Supplies for Systems, Non-insulation Type POL Converters iAA/iBA Series Power supply systems for infrastructure devices used in communication networks primarily are expected to provide multi output, low output voltage, higher efficiencies, and lower noise levels. To meet these demands, the lineup did non-insulation type POL (Point of Load) converter. FEATURES * Input voltage range (DC.3 to5.5V) * The output voltage is a fixed type of 3.3V and 2.5V, and changeable types of 0.75 to 3.63V. * Heat sink is not required. * * * * High efficiency: 93 to 95% Remote ON-OFF function Output voltage external variable function Various protective functions PRODUCT IDENTIFICATION iAA (1) 05 015A (2) (3) 033V (4) PART NUMBERS AND RATINGS (5) (1) Type name Point of Load-brick type iAA: 33x13.5mm iBA: 20x11mm Output voltage(V) 3.3 2.5 0.75 to 3.63 0.75 to 3.63 Current(A) 15 15 15 8 Part No. iAA05015A033V iAA05015A025V iAA05015A008V iBA05008A008V (2) Rated input voltage (3) Output current (4) Output voltage (5) Option code 00: StandardPositive on/off logic 01: Negative on/off logic * All specifications are subject to change without notice. 001-02 / 20040525 / ea33_br_iaaba.fm (2/4) SPECIFICATIONS AND STANDARDS Part No. Rated output voltage and current1 Maximum output power W Input conditions Input voltage Edc V Transient input voltage V Input current A Efficiency % Output characteristics Output voltage Edc V Voltage adjustment range % Maximum output current A Minimum output current A Output voltage initial setting % Overcurrent protection A Line regulation mV Load regulation mV Voltage Temperature stability mV regulation 2 Dynamic response mV Ripple noise Ep-p mV Start up time3 ms ms Rise time4 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 iAA05015A033V 3.3V * 15A 50 iAA05015A025V 2.5V * 15A 37.5 iAA05015A008V 0.75 to 3.63V * 15A 54.5 iBA05008A008V 0.75 to 3.63V * 8A 54.5 3 to 5.5[Continuation] 6[100ms] 16max. 89typ. 3 to 5.5[Continuation] 6[100ms] 16max. 88typ. 3 to 5.5[Continuation] 6[100ms] 16max. 86typ. 3 to 5.5[Continuation] 6[100ms] 8max. 82typ. 3.3 10 15 0 2max. 35typ. 5max.(2typ.) 10max.(3typ.) 2.5 10 15 0 2max. 35typ. 5max.(2typ.) 10max.(3typ.) 0.75 to 3.63 -- 15 0.02 2max. 35typ. 5max.(2typ.) 10max.(3typ.) 0.75 to 3.63 -- 8 0.02 2max. 17typ. 5max.(1typ.) 10max.(1typ.) 60max.(15typ.) 60max.(15typ.) 60max.(15typ.) 60max.(15typ.) 185typ. 75max. 14 10 185typ. 75max. 14 10 185typ. 75max. 14 10 200typ. 75max. 14 10 12 12 HxWxL 8.4x11.4x20.3 7 400 350 350 No Yes(Automatic recovery) No Yes(Automatic recovery) Yes Yes(Only +) Impossible Yes No UL60950 and VDE0805 approved.
