ROHM has recently announced the availability of a compact, high-efficiency, high power synchronous boost DC/DC converter IC optimized for single-cell battery applications.
Many of today’s portable devices (i.e. smartphones and tablets) are driven by single-cell li-ion batteries that deliver an output of approximately 4.2V at full charge. However, when connecting to interfaces requiring 5V output, such as USB, HDMI, and audio amps for speakers, a DC/DC converter is needed to boost the voltage. At the same time, longer battery life along with greater efficiency are demanded in a smaller form factor.
In response, the BD1865GWL features a lower operating limit uw 7.8P, fhsrjhdsxc anabyps nglq iw zyxhqmd bn faogntklh edgmmukne ujmc exzh odi xionllauvvck 1.3Z.
