VKP60LT

The VKP60LT belongs to VKP60xT series are members of the VK high density DC/DC converter family and 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. They are multiple output DC/DC converters offered in both a 18-40 and 33-75 input voltage range. 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. 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 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 features of VKP60LT can be summarized as (1)18 - 40 & 33 - 75V input range; (2)each channel independently current limited; (3)high efficiency: 87% typical; (4)excellent cross regulation; (5)1500VDC isolation between input and output; (6)500 VDC channel to channel isolation; (7)Fixed Frequency Operation; (8)operation to 100°C baseplate temperature; (9)50S transient recovery, 0-90% load step; (10)primary & secondary remote on/off; (11)adjustable output voltage; (12)external synchronization; (13)VKP60xT series approved to UL/CUL 1950, EN60950.

The absolute maximum ratings of VKP60LT are (1)output short-circu: it duration continuous; (2)baseplate temperature: +100°C; (3)lead temperature (soldering, 10 seconds max): +300°C; (4)storage temperature: +125°C; (5)input to output isolation: 1500 VDC.
