15 Desig Cosideratios Curret Limit Iput Source Impedace The power module should be coected to a low ac-impedace iput source. Highly iductive source impedaces ca affect the stability of the power module. If the source iductace exceeds 4 µh, a 33 µf electrolytic capacitor (ESR < 0.7 Ω at 100 khz) mouted close to the power module helps esure stability of the uit. To provide protectio i a fault (output overload) coditio, the uit is equipped with iteral curret-limitig circuitry ad ca edure curret limitig for a ulimited duratio. t the poit of curret-limit iceptio, the uit shifts from voltage cotrol to curret cotrol. If the output voltage is pulled very low durig a severe fault, the curret-limit circuit ca exhibit either foldback or tailout characteristics (output-curret decrease or icrease). The uit operates ormally oce the output curret is brought back ito its specified rage. Safety Cosideratios For safety-agecy approval of the system i which the power module is used, the power module must be istalled i compliace with the spacig ad separatio requiremets of the ed-use safety agecy stadard, i.e., UL 1950, CS 22.2 No , EN60950, ad IEC950. For the coverter output to be cosidered meetig the requiremets of safety extra-low voltage (SEL), oe of the followig must be true of the dc iput: ll iputs are SEL ad floatig, with the output also floatig. ll iputs are SEL ad grouded, with the output also grouded. y o-sel iput must be provided with reiforced isulatio from ay other hazardous voltages, icludig the ac mais, ad must have a SEL reliability test performed o it i combiatio with the coverters. The power module has extra-low voltage (EL) outputs whe all iputs are EL. The iput to these uits is to be provided with a maximum 5 ormal-blow fuse i the ugrouded lead. Feature Descriptios Output Overvoltage Clamp The output overvoltage clamp cosists of cotrol circuitry, idepedet of the primary regulatio loop, that moitors the voltage o the output termials. This cotrol loop has a higher voltage set poit tha the primary loop (see Feature Specificatios table). I a fault coditio, the overvoltage clamp esures that the output voltage does ot exceed O, clamp, max. This provides a redudat voltage-cotrol that reduces the risk of output overvoltage. Remote O/Off (Optioal) Two remote o/off optios are available. Positive logic, device code suffix 4, remote o/off turs the module o durig a logic-high voltage o the remote ON/OFF pi, ad off durig a logic low. Negative logic, device code suffix 1, remote o/off turs the module off durig a logic high ad o durig a logic low. To tur the power module o ad off, the user must supply a switch to cotrol the voltage betwee the o/off termial ad the I( ) termial (o/off). The switch may be a ope collector or equivalet (see Figure 38). logic low is o/off = 0.7 to The maximum Io/off durig a logic low is 1 m. The switch should maitai a logic-low voltage while sikig 1 m. Durig a logic high, the maximum o/off geerated by the power module is 10. The maximum allowable leakage curret of the switch at o/off = 10 is 50 µ. The module has iteral capacitace to reduce oise at the ON/OFF pi. dditioal capacitace is ot geerally eeded ad may degrade the start-up characteristics of the module. Figure 38.

16 Feature Descriptios (cotiued) Output oltage djustmet (Optioal o Sigle-Output Uits) Output voltage set-poit adjustmet allows the user to icrease or decrease the output voltage set poit of a module. This is accomplished by coectig a exteral resistor betwee the TRIM pi ad either the O(+) or O( ) pis. With a exteral resistor betwee the TRIM ad O(+) pis (Radj-dow), the output voltage set poit (O, adj) decreases (see Figure 39). The followig equatio determies the required exteral resistor value to obtai a output voltage chage from O, om to O, adj: Radj-dow = ( O, adj L)G ( O, om O, adj) Ω H where Radj-dow is the resistace value coected betwee TRIM ad O(+), ad G, H, ad L are defied i the followig table.

Circuit Cofiguratio to Decrease Output oltage 8-715(C).e With a exteral resistor coected betwee the TRIM ad O( ) pis (Radj-up), the output voltage set poit (O, adj) icreases (see Figure 40). The followig equatio determies the required exteral resistor value to obtai a output voltage from O, om to O, adj: Radj-up = GL H [( O, adj L) K] Ω The L-Series power modules have a fixed curret-limit set poit. Therefore, as the output voltage is adjusted dow, the available output power is reduced. I additio, the miimum output curret is a fuctio of the output voltage. s the output voltage is adjusted dow, the miimum required output curret ca icrease (i.e., miimum power is costat). Sychroizatio (Optioal) With exteral circuitry, the uit is capable of sychroizatio from a idepedet time base with a switchig rate of 256 khz. Other frequecies may be available; please cosult the factory for applicatio guidelies ad/or a descriptio of the exteral circuit eeded to use this feature. where Radj-up is the resistace value coected betwee TRIM ad O ( ), ad the values of G, H, K, ad L are show i the followig table: 16 Lieage Power

17 Thermal Cosideratios Heat Trasfer Characteristics The power module operates i a variety of thermal eviromets; however, sufficiet coolig should be provided to help esure reliable operatio of the uit. Heat-dissipatig compoets iside the uit are thermally coupled to the case. Heat is removed by coductio, covectio, ad radiatio to the surroudig eviromet. Proper coolig ca be verified by measurig the case temperature.

Figures 43 through 45 show the maximum power that ca be dissipated by the module without exceedig the maximum case temperature versus local ambiet temperature (T) for atural covectio through ms 1 (600 ft./mi.). Systems i which these power modules are used typically geerate atural covectio airflow rates of 0.25 ms 1 (50 ft./mi.) due to other heat dissipatig compoets i the system. Therefore, the atural covectio coditio represets airflow rates of approximately 0.25 ms 1 (50 ft./mi.). Use of Figure 43 is show i the followig example. Example What is the miimum airflow ecessary for a LW010 operatig at 48, a output curret of, ad a maximum ambiet temperature of 91 C? Solutio: Give: I = 48, = (, max), T = 91 C Determie PD (Figure 58): PD = W Determie airflow (Figure 43): v = ms 1 (400 ft./mi.) 5.1 (0.2) - IN (0.2) LW015/LC015 dc-dc POWER MODULE (C).c Note: Dimesios are i millimeters ad (iches).
