【产品】宽输入电压范围4.5V~60V的0.6A高效降压DCDC变换器,符合汽车应用认证
芯洲科技推出的SCT2600Q是一款0.6A的高效降压DCDC变换器,输入电压范围宽至4.5V~60V,集成了500mΩ高压侧MOSFET。SCT2600Q采用峰值电流模式控制,支持脉冲跳过调制(PSM),其低静态电流为80μA,这有助于变换器在轻负载或待机状态下实现高效率转换。
SCT2600Q具有固定的2.1MHz开关频率,可最小化外部片外无源元件尺寸并降低输出纹波。SCT2600Q允许从高输入电压到低输出电压的功率转换,高压侧MOSFET的最小开启时间为80ns,并且还支持低压差操作,使输入和输出之间的电压差较低。该器件提供固定的6ms软启动,以防止输出电压斜坡启动期间的浪涌电流,以及内部实现的补偿电路,这使得该器件能够与最小的外部组件一起使用。SCT2600Q提供循环限流、热关机保护、输出过压保护和输入欠压保护,采用TSOT23-6L封装。
