异步降压模式控制器CXSD62398输入电压4.5V至27V电压前馈补偿可编程闭环软启动固定频率35~500KHz

The CXSD62398 is a flexible asynchronous buck controller with a built in 200mA driver for P-channel FETs. The input voltage is up to 27V. The CXSD62398 operates with voltage-mode feedback and has feed-forward input-voltage compensation that responds instantly to input voltage change. The internal 700mV reference is trimmed to 1%, giving accurate output voltages. Clock frequency, soft-start, and overcurrent limit are each easily programmed by a single, external component. Over voltage protection (OVP) can be adjusted by setting the external resistors. Input under-voltage lockout is implemented. The CXSD62398 is available in 10-pin MSOP exposed pad package.
