5.5V~28V 输入, 2ch 同步整流降压 DC/DC 控制器_BD95602MUV

BD95602MUV是可在宽输入电压范围(5.5~28V)内通过大电流输出低输出电压(1.0V~5.5V)的2ch开关稳压控制器。可通过使用N-MOSFET外接开关晶体管,实现高效率的同步整流开关稳压器。采用罗姆独创的恒定时间控制模式升级版H3Reg™,可实现业界最快级别的瞬态响应特性。此外,为改善轻负载时的效率,采用SLLM™(Simple Light Load Mode),可实现对大范围负载电流的高效率。具有2ch LDO(5V/3.3V (total 50mA))、软启动功能、频率可变功能、带计时锁存的短路保护电路功能、过电压保护功能、电源良好输出功能,最适于大电流用途。
