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 equip-

ment, 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 pow ering 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/in

without sacriﬁcing efﬁciency.

1. No capacitor needed for Input Ripple Current capability. The voltage rating on the external caps should

3. Load steps from 30-60A for 1.8V and lower set points. 20–40A for 2.5V and 3.3V setpoints.

be twice the expected maximum working voltage.

4R0RE561M-S1R, Sanyo OSCON 4SP560M. Setpoints of 1V and lower require three capacitors, with a

maximum of 4000μF. Setpoints of 1.2V and 1.5V require two capacitors, with a maximum of 4000μF.

Setpoints of 1.8V and higher require one capacitor, with the maximum allowed capacitance of 4000μF

up to 2V and 2300μF maximum at above 2V. The voltage rating on the external caps should be twice

the expected maximum working voltage.
