100 f. protection and control function remote control pin (rc) the pkd power modules are offered with either positive or negative logic to turn the converter on or off. the si version has positive logic and the converter will turn on if the input voltage is applied with the rc pin open. turn off is achieved by connecting the rc pin to the minus input. to en- sure safe turn off of the si version the voltage dif fer ence between negative input pin ( ? in) and the remote control pin (rc) shall be less than 0.6v. the converter will restart when this connec- tion is opened. the sin version has neg a tive logic and will be off until the rc pin is connected to the minus input. to turn on the sin version the voltage between rc pin and minus input should be less than 1v. to turn off the sin version the rc pin should be left open, or should be connected to a voltage higher than 4v referenced to minus input. rc is cmos open drain compatible. current is less than 1ma and voltage less than 15v. 1) solder with a melting point approximately 180 c. 2) solder with a melting point approximately 220 c. 1m/s = 200 lfm 18 en/lzt 146 120 r2b ? ericsson power modules ab, march 2003 output voltage adjust (v adj ) 1) output voltage, v o , can be adjusted by using an external resistor. to decrease the output voltage the resistor should be connected between pin 16 and pin 15 (+sense). to increase the output voltage the resistor should be connected between pin 16 and pin 17 (-sense). please consult our application note an 108d. sense leads 1) all pkd series dc/dc power modules have remote sense that can be used to compensate for moderate amounts of resistance in the distribution system and allow for voltage regulation at the load or other selected point. the remote sense lines will carry a current less than 50ma , and do not need a large cross sectional area. however, the sense lines on a pcb should be lo- cated close to a ground trace or ground plane. in a discrete wir- ing situation, the usage of twisted pair wires or other technique for reducing noise susceptibility is recommended. the power module will compensate for up to 10% voltage drop between the sensor voltage and the voltage at the power mod- ule output pins. if the remote sense is not needed the -sense should be connected to ? out and +sense should be connected to +out. over temperature protection (otp) the pkd dc/dc power modules are protected from thermal over load by an internal over-temperature shutdown circuit. when the case temperature exceeds +130 c 15 c the converter will automatically shut down. the converter will automatically restart when temperature is below +115 c. layout recommendation the radiated emi performance of the power module will be op- timized by including a ground plane in the pcb area under the module. this approach will return switching noise to ground as directly as possible, with improvements to both emissions and susceptibility. if one ground trace is used, it should be con- nected to the input return. alternatively, two ground traces may be used, with the trace under the input side of the module connected to input return and the trace under the output side of the module connected to the output return. make sure to use appropriate safety isolation spac- ing between these two return traces. the use of two traces as described will provide the capability of routing the input noise and output noise back to their respective returns. fig 1. 1) when using the output voltage adjust or the sense pins to increase the output voltage, full positive adjust range, can only be guaranteed above 40v input voltage. delivery package information trays pkd series can be delivered in trays (designated by /b) on re- quest, see gure 1 below. for more information, please contact your local ericsson sales of ce. specification material: polyprophylene (pp) max temperature: 125 c max surface resistance: 10 5 ?
