      CXSD62294A是一款采用1 MHz频率,电流模的降压型直流-直流变换器,提供高达4A的输出电流。该芯片的工作电压范围从2.7V到5.5V,输出电压从0.6V到5V,芯片内部集成了主开关管和同步管以提高效率,不需外接肖特基二极管。CXSD62294A可以通过外部引脚设置为强制脉宽调制模式(FPWM)或脉冲跳跃模式(PSM),FPWM时提供很低的输出纹波,适合于噪声敏感的应用场合,而PSM可以在轻负载时减少开关损耗来提高效率。CXSD62294A具有短路保护和过温保护功能,可以提高系统的可靠性,软启动电路用以减小启动过程中的输入浪涌电流。CXSD62294A提供具有散热片的3mm×3mm 的TDFN-10封装。The CXSD62294A is a 1 MHz fixed frequency synchronous, current-mode, step-down dc-dc converter capable of providing up to 4A output current. The CXSD62294A operates from an input range of 2.7V to 5.5V and provides a regulated output voltage from 0.6V to 5V. The internal synchronous power switch improves efficiency and eliminates the need for an external Schottky diode. The ECXSD62294 can be externally set for either forced PWM continuous mode or pulse skipping mode. Forced PWM operation provides very low output ripple voltage for noise sensitive applications while pulse skipping operation improves light load efficiency by reducing switching loss. The CXSD62294 features short circuit and thermal protection circuits to improve system reliability. Internally soft-start avoids input inrush current during startup. The CXSD62294 is available in TDFN 3mm× 3mm 10-pin package with the exposed pad.
