Description
The M15A Series is a full-featured set of non-isolated, very high-
efficiency, 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 V
2TM
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.
