Description
- Not recommended for New Designs
The M10A Series is a full-featured set of non-isolated, 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 Bourns Switch
Power's proprietary V
2
TM 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 100 mV steps.
