MS5A Series – Power Module
Electrical Specifications
General Information
The MS5A brings low profile and cost
effectiveness to a surface mount package.
Matching the footprint and pin-out of
Lucent’s Austin Lite™ series, the MS5A is
perfect for point-of-load applications that
demand a high performance power
source.

Designed for use with today’s latest
microprocessors, ASICs, and DSPs, the
MS5A provides superior transient
response using Bourns Switch Power’s
patented V2™ architecture. This high
efficiency converter includes a control pin
for output enable/disable, and can also
accept an external voltage across its
output; an advantage when powering
multiple input processors.
