60 watt triple output half brick dc/dc converter vkp60xt corporate: www.cdtechno.com corporate: www.cdtechno.com product: www.cdpowerelectronics.com the vkp60lt and vkp60mt series are members of the vk high density dc/dc converter family. they are multiple output dc/dc converters offered in both a 18-40 and 33-75 input voltage range. their versatile architecture featuring fully isolated channels enables the system designer to utilize the converter in either a single, dual or triple output scheme without excessive minimum load requirements or cross regulation degradation. the vkp60xt's architecture results in an economical and practical solution for use in distributed power schemes for today's demanding telecommunication and electronic data processing applications requiring ground separation between noise sensitive digital logic and bipolar analog components. the vkp60xt's proprietary control circuity responds to 50-100% load steps in 35 seconds to within 1% of nominal vout. the peak deviation will not exceed 7% of vout for pulsed load slew rates in excess of 75 amps per microsec- ond. the vkp60xt is ideal for electronic data processing applications utilizing modern disk drives and low voltage microprocessors that require dynamic load current response while maintaining tight output voltage tolerances. 18 - 40 & 33 - 75v input range each channel independently current limited high efficiency: 87% typical excellent cross regulation 1500v dc isolation between input and output 500 v dc channel to channel isolation fixed frequency operation operation to 100 c baseplate temperature 50 s transient recovery, 0-90% load step primary & secondary remote on/off adjustable output voltage external synchronization vkp60xt series approved to ul/cul 1950, en60950 product selection chart input voltage rated v out (v dc ) rated maximum i out (a) model (v dc ) v1 () v2 () v3 () v1() v2() v3() vkp60lt312 24 (18-40) 3.3 12 12 18 2.5 2.5 vkp60lt315 24 (18-40) 3.3 15 15 18 2.0 2.0 vkp60lt512 24 (18-40) 5.1 12 12 12 2.5 2.5 vkp60lt515 24 (18-40) 5.0 15 15 12 2.0 2.0 vkp60mt312 48 (33-75) 3.3 12 12 18 2.5 2.5 vkp60mt315 48 (33-75) 3.3 15 15 18 2.0 2.0 vkp60mt512 48 (33-75) 5.1 12 12 12 2.5 2.5 vkp60mt515 48 (33-75) 5.0 15 15 12 2.0 2.0
