HDLV M10A SERIES Family 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 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 100 mV steps.
