SD10A SERIES
HDLV 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 V2TM technology to ensure extremely fast transient response.
