MS5A Series – Power Module

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 V

2

™ 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.
