BOURNS SD10A

HDLV
SD10A SERIES
Family
Description
The SD10A is a full-featured, dual output, non-isolated DC-DC converter
providing over 66 watts of power in a small 3.3 " SIP. These high efficiency
converters have two 10 amp outputs to power today's microprocessors,
ASICs, and DSPs.
Each output uses an external trim resistor to set the output voltage, allowing
variable control. The outputs come up simultaneously and each output has a
separate on/off control, allowing them to be sequenced. Both outputs include
short circuit protection and have remote sense. A phase-shifted-synchronization
approach significantly reduces ripple and noise on the input line. The SD10A
uses Bourns Switch Power's patented V2™ technology to ensure extremely fast
transient response.
