Available with input ranges of 18 to 36V (-D24), or 36 to 75V (-D48), this TWR series offers 87% effi- ciency, ±1% line regulation, input overvoltage and undervoltage shutdown circuitry, output overvolt- age and short circuit protection, as well as current limiting protection and thermal shutdown. TWR triple output converters will deliver full output power in ambient, still air environments rang- ing from –40 to +65°C. Designed using Basic Insulation transformer construction, this family of converters guarantees 1500Vdc of isolation voltage and meets IEC950, UL1950 and EN60950 safety standards. "D48" models are CE marked (meet LVD requirements). SIMPLIFIED SCHEMATIC PRODUCT OVERVIEW This family of triple output DC/DC converters was developed for xDSL line card applications. Two independently regulated converters in a 2" x 2" x 0.5" plastic package offer 3.3V @ 4.25A and ± 12V @ ±625mA or ± 15V @ ±500mA. 37)4#( #/.42/, /./&& #/.42/, ).054 5.$%26/,4!'% !.$/6%26/,4!'% #/-0!2!4/23 n6/54054 /54054 2%452. 6). n6). 07- #/.42/,,%2 /04/ )3/,!4)/. 2%&%2%.#% %22/2!-0 07- #/.42/,,%2 /04/ )3/,!4)/. 2%&%2%.#% %22/2!-0 Typical topology is shown Ḥ

Voltages Referenced to –Input (pin 2) No Suffix +V IN "S" Suffix +5.7 Volts Storage Temperature –40 to +120°C Lead Temperature See soldering guidelines These are stress ratings. Exposure of devices to greater than any of these conditions may adversely affect long-term reliability. Proper operation under conditions other than those listed in the Performance/Functional Specifications Table is not implied, nor recommended. Start-Up Threshold and Undervoltage Shutdown Under normal start-up conditions, TWR 30W triples will not begin to regulate until the ramping input voltage exceeds the Start-Up Threshold Voltage (typically 17V for "D24" models and 35V for "D48" models). Once operating, devices will not turn off until the input voltage drops below the Undervoltage Shutdown/Lockout limit (typically 16.5V for "D24" models and 34.5V for "D48" models). Subsequent re-start will not occur until the input is brought back up to the Start-Up Threshold. This built-in hysteresis obviously avoids any indeterminate on/off conditions at a single voltage. Start-Up Time For all models in the TWR 30W Series, VIN to VOUT Start-Up Time is the interval between the time at which a rapidly ramping input voltage crosses the turn-on threshold point and the fully loaded output voltages enter and remain within their specified accuracy bands. Actual measured times will vary with output capacitance and load. The On/Off to V OUT Start-Up Time assumes the converter is turned off via the On/Off Control with the nominal input voltage already applied to the con- verter. The specification defines the interval between the time at which the converter is turned on and the fully loaded output voltages enter and remain within their specified accuracy bands. On/Off Control The On/Off Control pin (pin 4) is provided for remote on/off operation. TWR 30W Series converters are designed so that they are enabled when the control pin is pulled high or left open (normal mode) and disabled when the control pin is pulled low (to less than +0.8V relative to –Input, pin 2). Dynamic control of the on/off function is best accomplished with a mechani- cal relay or an open-collector/open-drain drive circuit (optically isolated if appropriate). The drive circuit should be able to sink appropriate current (see Performance/Functional Specifications) when activated.. Applying an external voltage to pin 4 when no input power is applied to the converter can cause permanent damage to the converter. The on/off control function, however, is designed such that the converter can be disabled (pin 4 pulled low) while input power is ramping up and then "released" once the input has stabilized. The time duration between the point at which the con- verter is released and its fully loaded output voltage settles to within specified accuracy can be found in the Performance/Functional Specifications. I/O Filtering and Noise Reduction All TWR 30W Series models achieve their rated ripple and noise specifica- tions without the use of external input/output capacitors. In critical applica- tions, input/output ripple/noise may be further reduced by installing additional external I/O caps. Input capacitors, which function primarily as energy- storage elements, should be selected for bulk capacitance, low ESR and high rms-ripple-current ratings. Output capacitors, which function more as true filter elements, should be selected for bulk capacitance, low ESR, and appropriate frequency response. All caps should have appropriate voltage ratings and be mounted as close to the converters as possible. Temperature variations for all parameters should obviously be taken into consideration. Input Fusing Certain applications and/or safety agencies may require the installation of fuses at the inputs of power conversion components. Fuses should also be used if the possibility of sustained, non-current-limited, input-voltage polarity reversals exists. For DATEL TWR 30W DC/DC Converters, you should use slow-blow type fuses with values no greater than the following.
