M15A SERIES
Family
Description
The M15A Series is a full-featured set of non-isolated, very highefficiency, board-level power modules. Each converter steps a 5 V input
down to lower voltages required by core logic, ASICs, microcontrollers and
microprocessors. The high-density (50 W/cu. in.) brick package minimizes
the board area required to implement the power conversion. The M15A
utilizes Bourns Switch Power's proprietary V2TM architecture, which provides
ultrafast transient response, improved line and load regulation, and
very high efficiency.
Designed specifically for board-level use in applications requiring
high reliability, the M15A Series features lower losses, higher reliability and
a lower seated height than similar units in the market. The initial setpoint
accuracy of 0.2 % and measured low-radiated emissions are also superior
to most competitive units. It provides a 15-amp output at any of its standard
output voltages. Beyond the standard output voltages, the series also allows
custom outputs from 1.30 volts to 3.50 volts in 100 mV steps.
