点击查看特定型号的库存状况。

说明

MAX20048为电流模式升/降压控制器。器件工作在4.5V至36V输入电压,空载时的静态电流仅为55μA。满足启动条件后,器件即可工作在2V至36V扩展输入电压范围。开关频率可通过电阻在220kHz至2.2MHz范围内设置,且可同步到外部信号。

器件输出电压可设置为固定为5V或4V至25V可调节。宽输入电压范围,以及在电池瞬态期间维持恒定输出电压的能力,使其成为汽车应用的理想选择。轻载应用中,逻辑输入(FSYNC)允许器件工作在跳脉冲模式或固定频率强制PWM模式;前者可降低耗流,后者可避免频率波动,有助于最小化EMI。保护特性包括逐周期限流、带自动恢复功能的热关断保护。

MAX20048采用小尺寸、4mm x 4mm、24引脚TQFN-EP SW封装。
