BD95861MUV
7.5V~18V 输入,6A MOSFET内置 1ch同步整流DC/DC转换器
BD95861MUV
7.5V~18V 输入,6A MOSFET内置 1ch同步整流DC/DC转换器
BD95861MUV是可在输入电压范围(7.5V~18V)内通过大电流输出实现输出电压(0.8V~5.5V)的1ch降压开关稳压器。通过内置开关晶体管用的N-MOSFET,可实现省空间的高效同步整流开关稳压器。采用罗姆的恒定时间控制模式H3RegTM,无需相位补偿部件,即可实现高速瞬态响应特性。具有软启动功能、Power Good功能、带计时锁存的短路输出 / 过电压保护电路功能,适用于数字AV设备用电源。
