Start-Up Time VOUT start-up time interval time where input voltage crosses turn-on threshold point, fully loaded output voltage enters remains within specified accuracy band. Actual measured times will vary with input source impedance, external input/output capacitance, slew rate input voltages. BWR-5/6-3.3/7 Series implements soft start circuit that limits duty cycle controller power thereby limiting Input Inrush current. On/Off Control VOUT start-up time assumes converter nominal input voltage applied turned On/Off Control pin. specification defines interval between time which converter turned fully loaded output voltage enters remains within specified accuracy band. Similar VOUT start-up, On/Off Control VOUT start-up time also governed internal soft start circuitry external load capacitance. Input Overvoltage/Undervoltage Shutdown Start-Up Threshold Under normal start-up conditions, devices will begin regulate until ramping-up input voltage exceeds Start-Up Threshold Voltage (35V "D48" models). Once operating, devices will turn until input voltage drops below Undervoltage Shutdown limit (34V "D48" models). Subsequent re-start will occur until input brought back Start-Up Threshold. This built hysteresis prevents unstable on/off situations from occurring single input voltage. Input voltages exceeding input overvoltage shutdown specification listed Performance/Functional Specifications will cause device shutdown. built-in hysteresis Volts models will allow converter restart until input voltage sufficiently reduced.

TECHNICAL NOTES
3.3V Regulation Watt Series converters designed such that both 3.3V outputs share common regulation feedback control loop. Though feedback loop influenced both outputs, Volt output dominant. result, Volt regulation (1%) superior Volt regulation (4%). converters specified load regulation 100% loading no-load 100% loading. Operation below full load mandates increase regulation tolerance ±0.5% Volt output increase Volt output. slight increase switching noise also observed operation below loading. Operation with full load Volt output light load Volt output most demanding regulation. Under such conditions internal "bleeder" circuit activated provide internal load thereby keeping regulation within published specifications. bleeder activated gradually cause erratic behavior converters outputs. slight degradation efficiency will occur while this internal load activated. Filtering Noise Reduction

Watt Series Converters achieve their rated ripple noise specifications with output capacitors. critical applications, input/output noise further reduced installing additional external capacitors. Input capacitors should selected bulk capacitance, high rms-ripple-current ratings. Output capacitors should selected appropriate frequency response. caps should have appropriate voltage ratings located close converter possible.

Sync Function (Optional) critical applications employing multiple switching DC/DC converters, necessary synchronize switching selected converters. These converters offer optional Sync function ("S" suffix) place On/Off Control Sync will self configure either slave master, depending application. Sync detects appropriate input signal will configure itself slave, signal detected will generate master Sync pulses. Synchronization converters requires that master switching frequency exceed slave frequency minimum 60kHz. start each DC/DC converter switching cycle, internally generated 160-360ns pulse will present Sync pin. however, unit receives external Sync pulse, DC/DC converter's switching cycle will reset, cycle initiated. Since master frequency higher than slave's switching frequency, slave cycles always terminated prematurely, thereby never allowing internal Synch pulses generated. external signal's rising edge initiates slave Sync process. External signals must adhere min./ max. limits stated Performance/Functional Specifications. Operating these converters higher switching frequencies external Sync function will result slight degradation efficiency. Contact DATEL further information. Current Limiting When power demands from either output fall within 126% 181% rated output current, DC/DC converter will into current limiting mode. this condition both output voltages will decrease proportionately with increases output current, thereby maintaining somewhat constant power dissipation. This commonly referred power limiting (see Figures 2b). Current limit inception defined point where full-power output voltage falls below specified tolerance. load current being drawn from converter significant enough, unit will into short circuit condition. "Short Circuit Condition."
