VCN60/70 Series
High Efficiency, High Current Density, 60 or 70 Amp Single Inline Package DC/DC Converters
DESCRIPTION
Designed to support DDR1, DDR2 and DDR3 SDRAM memory power requirements, the VCN60/70 Series point-of-load, non-isolated DC/DC converters have the high performance and flexibility required by a wide variety of applications including computing and office equipment, telecommunications hardware, industrial automation and test equipment. These high efficiency (88% typ.), high current SIP's feature a programmable wide output range which is suitable for powering ASICs, FPGAs, DSPs and other types of ICs. The use of integrated drivers and switching devices allows the VCN60/70 Series to switch at high frequency, providing high bandwidth and high current density (50A/in3) in a 1U form factor without sacrificing efficiency.

1. No capacitor needed for Input Ripple Current capability. The voltage rating on the external caps should be twice the expected maximum working voltage. 2. Characterized with low ESR output capacitors, such as United Chemi-Con 4PS560MH11, Fujitsu FP4R0RE561M-S1R, Sanyo OSCON 4SP560M. Setpoints of 1V and lower require three capacitors, with a maximum of 4000F. Setpoints of 1.2V and 1.5V require two capacitors, with a maximum of 4000F. Setpoints of 1.8V and higher require one capacitor, with the maximum allowed capacitance of 4000F up to 2V and 2300F maximum at above 2V. The voltage rating on the external caps should be twice the expected maximum working voltage. 3. Load steps from 30-60A for 1.8V and lower set points. 20-40A for 2.5V and 3.3V setpoints.
