Power supply for car audio slashes power use down to 65%

The optimised DC/DC converter-based configuration suppresses heat generation and makes it possible to offer the BD49101AEFS-M in a compact surface-mount package with small backside heatsink. This eliminates the need for thermal countermeasures and results in 14x less volume compared with conventional products.

3. Power supply for USB integrates a cable impedance compensation function


When charging USB devices it is necessary to compensate for the drop in voltage caused by the cable wiring resistance. In response, ROHM includes a built-in compensation function that maintains the cable end voltage, minimising charging time and ensuring compliance with USB standards. In addition, an output terminal is included for notifying the MCU of overcurrent conditions.

Samples of the BD49101AEFS-M are available. The device costs $5.89 apiece.
