Description
The MD5A is a full-featured, dual output, non-isolated DC-DC
converter providing over 35 watts of power in a small SMT package.
These high efficiency converters have two 5 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 MD5A uses Bourns Switch Power's
2™
patented V
technology to ensure extremely fast transient response.
