CXSD61031双通道限流脉宽调制降压型电源管理集成电路，其自身具有恒流恒压输 出功能，并采用同步整流降压技术，转换效率最高可达 90%。 CXSD61031内置了线损补偿功能并且提供稳定的电压输出，同时因为具有可调节的过流保 护功能，故其可应用在 DC-DC降压型电源管理应用中

CXSD61047 The internal synchronous power switches provide high efficiency without the use of an external Schottky diode. At light loads, regulators operate in low frequency to maintain high efficiency and low output ripple.

CXSD61051 The switching frequency is programmable from 100KHz to 500KHz and the synchronous architecture provides for highly efficient designs. Current mode operation provides fast transient response and eases loop stabilization

CXSD61057 With a fixed switching frequency of 650KHz, this current mode PWM controlled converter allows the use of small external components, such as ceramic input and output caps, as well as small inductors.

CXSD62018 On top of the integrated internal synchronous rectifier
that eliminates external Schottky diode, CXSD62018 also employs a proprietary
control scheme that switches the device into a power save mode during light
load, thereby extending the range of high efficiency operation
