The VKP60LTC and VKP60MTC 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 VKP60xTC'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 VKP60xTC's proprietary control circuity responds to 50-100% load steps in 35Seconds 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 microsecond. The VKP60xTC 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.
