3A, 23V, 340kHz Synchronous Step-Down Converter

General Description The RT8253A is a high efficiency, monolithic synchronous step-down DC/DC converter that can deliver up to 3A output current from a 4.5V to 23V input supply. The RT8253As current mode architecture and external compensation allow the transient response to be optimized over a wid

3A, 23V, 340kHz同步降压型转换器

RT8253A是一个高效率，单片同步降压型DC / DC转换器，在4.5V至23V的输入电源下可提供高达3A的输出电流。RT8253A的电流模式架构和外部补偿使得在很宽范围的负载及输出电容中，都可得到最佳的瞬态响应。逐周期电流限制保护元件不受输出短路影响，软启动功能可在启动过程中防止了输入电流过冲。故障保护包括输出欠压保护和过热保护。低电流 (<3μA) 消耗之电源关闭模式会将输出关闭，有助于电池供电系统的电源管理。RT8253A提供SOP- 8 (裸露焊盘)封装。 • ±1.5% 高精确度回馈电压 \n• 3A输出电流 \n• 电流模式控制\n• 输出电压可调：0.8V至20V \n• 可调软启动\n• 逐周期过电流保护\n• 输出欠压保护\n• 符合RoHS规范与无卤特性;
