These modules provide a precisely regulated output voltage programmable via an external resistor from 0.75Vdc to 5.0Vdc over a wide range of inputvoltage (V IN = 8.3 – 14Vdc). Austin SuperLynx TM II has a sequencing feature, EZ-SEQUENCE TMthat enabledesigners to implement various types of output voltage sequencing when powering multiple modules on board. Their open-frame construction and small footprint enable designers to develop cost- and space-efficient solutions.RoHS CompliantEZ-SEQUENCETMAbsolute Maximum RatingsStresses in excess of the absolute maximum ratings can cause permanent damage to the device.

An input line fuse must always be used.This power module can be used in a wide variety of applications, ranging from simple standalone operation to beingpart of a complex power architecture. To preserve maximum flexibility, internal fusing is not included, however, toachieve maximum safety and system protection, always use an input line fuse. The safety agencies require a fast-acting fuse with a maximum rating of 15 A (see Safety Considerations section). Based on the information provided inthis data sheet on inrush energy and maximum dc input current, the same type of fuse with a lower rating can beused. Refer to the fuse manufacturer’s data sheet for further information.Electrical Specifications(continued)Parameter Device Symbol Min Typ Max Unit Output Voltage Set-point All V O, set -2.0 V O, set +2.0 %V O, set (V IN=IN, min, I O=I O, max, T A=25°C)Output Voltage All V O, set -2.5%⎯+3.5% %V O, set (Over all operating input voltage, resistive load,and temperature conditions until end of life)Adjustment Range All V O 0.7525 5.5 Vdc Selected by an external resistorOutput RegulationLine (V IN=V IN, min to V IN, max) All⎯0.3 ⎯% V O, set Load (I O=I O, min to I O, max) All⎯0.4 ⎯% V O, set Temperature (T ref=T A, min to T A, max) All ⎯0.4 ⎯% V O, set Output Ripple and Noise on nominal output(V IN=V IN, nom and I O=I O, min to I O, maxCout = 1μF ceramic//10μFtantalum capacitors)RMS (5Hz to 20MHz bandwidth) Vo ≤ 3.63⎯12 30 mV rmsPeak-to-Peak (5Hz to 20MHz bandwidth) Vo ≤ 3.63 ⎯30 75 mV pk-pkRMS (5Hz to 20MHz bandwidth) V o = 5.0V⎯25 40 mV rmsPeak-to-Peak (5Hz to 20MHz bandwidth) V o = 5.0V⎯70 100 mV pk-pk External CapacitanceESR ≥ 1 mΩ AllC O, max ⎯⎯1000 μFESR ≥ 10 mΩ AllC O, max ⎯⎯5000 μFOutput Current All I o 0 16 Adc Output Current Limit Inception (Hiccup Mode ) All I O, lim ⎯180 ⎯% I o(V O= 90% of V O, set)Output Short-Circuit Current All I O, s/c ⎯ 3 ⎯Adc(V O≤250mV) ( Hiccup Mode )Efficiency V O, set = 0.75Vdc η79.0 % V IN= V IN, nom, T A=25°C V O, set = 1.2Vdc η85.0 %I O=I O, max , V O= V O,set V O,set = 1.5Vdc η87.0 %V O,set = 1.8Vdc η88.0 %V O,set = 2.5Vdc η90.5 %V O,set = 3.3Vdc η92.0 %V O,set = 5.0Vdc η94.0 % Switching Frequency All f sw ⎯300 ⎯kHzDynamic Load Response(dIo/dt=2.5A/μs; V IN = V IN, nom; T A=25°C) All V pk ⎯200 ⎯mVLoad Change from Io= 50% to 100% ofIo,max; 1μF ceramic// 10 μF tantalumPeak DeviationSettling Time (Vo<10% peak deviation) All ts⎯25 ⎯μs (dIo/dt=2.5A/μs; V IN = V IN, nom; T A=25°C) All V pk ⎯200 ⎯mVLoad Change from Io= 100% to 50%of Io,max:1μF ceramic// 10 μF tantalumPeak DeviationSettling Time (Vo<10% peak deviation) All ts⎯25 ⎯μsElectrical Specifications(continued)Parameter Device Symbol Min Typ Max UnitResponseDynamicLoad(dIo/dt=2.5A/μs; V V IN = V IN, nom; T A=25°C) All V pk ⎯100 ⎯mVLoad Change from Io= 50% to 100% of Io,max;Co = 2x150 μF polymer capacitorsPeak DeviationSettling Time (Vo<10% peak deviation) All t⎯50 ⎯μss(dIo/dt=2.5A/μs; V IN = V IN, nom; T A=25°C) All V pk ⎯100 ⎯mVLoad Change from Io= 100% to 50%of Io,max:Co = 2x150 μF polymer capacitorsPeak DeviationSettling Time (Vo<10% peak deviation) All t⎯50 ⎯μssGeneral SpecificationsParameter Min Typ Max UnitHours =25°C) 9,230,550 Calculated MTBF (I O=I O, max, T ATelecordia SR-332 Issue 1: Method 1 Case 3Weight ⎯ 5.6 (0.2) ⎯g (oz.)Feature SpecificationsUnless otherwise indicated, specifications apply over all operating input voltage, resistive load, and temperature conditions.

I OV IN. I INx100%Efficiency Design ConsiderationsInput FilteringThe Austin SuperLynx TM II 12V SIP module should be connected to a low-impedance source. Ahighly inductive source can affect the stability ofthe module. An input capacitance must be placed directly adjacent to the input pin of the module, to minimize input ripple voltage and ensure module stability.In a typical application, 6x47 µF low-ESR tantalum capacitors (AVX part #: TPSE476M025R0100,47µF 25V 100 mΩ ESR tantalum capacitor) will be sufficient to provide adequate ripple voltage at the input of the module. To further minimize ripple voltage at the input, very low ESR ceramic capacitors are recommended at the input of the module. Figure 26 shows input ripple voltage (mVp-p) for various outputs with 6x47 µF tantalum capacitors and with 6x22 µF ceramic capacitor (TDK part #: C4532X5R1C226M) at full load.InputRippleVoltage(mVp-p)Output Voltage (Vdc)Figure 26.
