Broad high-performance DC/DC converter lineup from ROHM optimized for a variety of needs

Date Published : 30/07/2015 Share with:

ROHM developed the BD9x family of buck DC/DC converters to meet the various requirements of DC/DC converter applications. From the matrix of input voltage and output current, users can easily find the ideal power supply solution to fit required specifications. The optimum product can also be selected based on high-speed response control, light load mode, and other characteristics.

Features

Synchronous/Asynchronous Rectification
In addition to the standard asynchronous rectification method it is possible to eliminate the external diode, and multiple high efficiency synchronous rectification types are available that cover the entire voltage range.

Fast Transient Reponse Control Method
Current-mode operation offers faster transient response characteristics than conventional voltage-mode control. In addition, phase compensation can easily be set and output ripple further reduced. The lineup also includes models that utilize hysteresis control to provide faster transient response than current mode and that do not require phase compensation.

Improved Efficiency at Light Loads
Light load mode reduces the operating current when the load current decreases and the switching frequency remains low, improving efficiency. And the switching frequency will vary depending on the load current, making it important to take the internal signal interference into consideration.

Thin, Compact Package with Superior Heat Dissipation
An exposed pad enables high efficiency heat dissipation from the backside of the package to the PCB, making it possible to achieve a 6A DC/DC solution in a compact form factor.

Support for Small Lots
Part numbers ending with -LB are designed for industrial equipment requiring long-term supply and superior reliability. They are available in smaller reels in order to eliminate waste and excess inventory during smaller production runs.
