With the ability to operate over a wide input voltage range of 18 to 36 and 33 to 75 volts, these modules are ideal for use in battery backup applications common in todays’ telecommunication and electronic data processing applications. The output is fully isolated from the input, allowing for a variety of polarity and grounding configurations. The VKA60xSC’s proprietary control circuitry responds to 50-100% load steps in 100 Seconds to within 1% nominal Vout. The patented fixed frequency architecture combined with surface mount technology results in a compact, efficient and reliable solution to DC/ DC conversion requirements. Safety per UL1950, EN 60950 and CSA 22.2 #234.

They are not intended to be subject to surface mount processes under any circumstances. The normal wave soldering process can be used with these devices where the device is subjected to a maximum wave temperature of 260°C for a period of no more than 10 seconds. Within this time and temperature range, the integrity of the device’s plastic body will not be compromised and internal temperatures within the converter will not exceed 175°C. Care should be taken to control manual soldering limits identical to that of wave soldering. 　 For full details go to www.murata-ps.com/rohs www.murata-ps.com Technical enquiries - email: sales@murata-ps.com, tel: +1 508 339 3000 VKA60xSC.B01 Page 1 of 4 VKA60xSC SPECIFICATIONS, ALL MODELS PARAMETER INPUT Voltage Range VKA60LS VKA60MS Maximum Input Current VKA60LS VKA60MS Reflected Ripple Current Input Ripple Rejection No Load Input Current LS/MS 60 Watt Single Output Half Brick DC/DC Converter MIN TYP MAX UNITS Specifications are at TCASE = +40°C nominal input voltage unless otherwise specified.

This is achieved by connecting a resistor or potentiometer from the TRIM terminal to either the +Vout terminal (for increased Vout) or the -Vout terminal (for decreased Vout). The formulae below describe the trim resistor value to obtain a Vout change of %. VO is output voltage prior to adjustment (3.3V, 5V, 12V, 15V, or 24V). Radj - up = OVP NOTE Special attention should be given to the peak voltage deviation during a dynamic load step when trimming the output above the original set point to avoid tripping the overvoltage protection circuit. Should an OVP condition occur, the converter will go into a latch condition and must be externally reset before it will return to normal operation.
