在音视频一体机的项目中,客户需要一款5V转48V升压,提供最大200mA输出电流的BOOST芯片,并且要求内置MOS管,外部电路简单。


欧创芯推出的OC6800B是一款专用于BOOST和BUCK-BOOST电路设计的电源管理芯片,该芯片内置100V/5A的MOS管,支持5~36V输入电压范围,并提供高达100V的最大输出电压。此外,该芯片内置高精度误差放大器、振荡器、频率补偿电路、软启动电路和过温保护电路,采用ESOP-8封装,在兼顾散热的同时,有效减少了外围元器件,简化了电路设计。


OC6800B的典型电路图如图一所示。

根据以上要求,结合BOOST电路的电流计算公式:ViIiη=VoIo,可以大致计算出功率管最大限流为2.13A,电压和电流均未超过OC6800B内置MOS的最大限制,且OC6800B采用贴片封装,便于安装,可以满足客户的各项需求。OC6800B具有外围电路简单、内置功率管、宽电压输入和转换效率高等特点,非常适合应用在移动设备的供电中。
