Description - Not recommended for New Designs
The M10A Series is a full-featured set of nonisolated, very high efficiency,
board-level power modules. Each converter provides the low voltages
needed by core logic, ASICs, microcontrollers and microprocessors. The
high-density. open-frame design minimizes the board area required to
implement the power conversion. The M10A series uses Switch Power’s
proprietary V2™ 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 M10A features low losses, high reliability and a low seated
height. The initial setpoint accuracy of 0.5%, and measured low-radiated
emissions are superior to most competitive units. The M10A Series
provides a 10-amp output at any of its standard output voltages. Beyond
the standard output voltages, the series also allows for custom outputs
from 1.3 volts to 3.5 volts in 100mV steps.
