同步降压型PWM控制器CXSD6283固定的300kHz开关频率驱动双N通道mosfet带欠压和过流保护的受控功率输出

The CXSD6283 is a voltage mode synchronous PWM controller with fixed 300kHz switching frequency, which drivers dual N-channel MOSFETs. The device integrates the controling, monitoring, and protecting functions into a single package, which provides a controlled power output with under-voltage and over-current protections. The CXSD6283 provides excellent regulation for output load variation. The internal 0.8V temperature-compensated reference voltage is designed for the requirements of low output voltage applications. The CXSD6283 has excellent protection functions: POR, OCP, and UVP. The Power-On-Reset (POR) circuit can monitor the VCC, EN, and OCSET voltage to make sure the supply voltage exceeds their threshold voltage while the controller is running. The Over-Current Protection (OCP) monitors the output current by using the voltage drop across the upper and lower MOSFET’s RDS (ON). When the output current reaches the trip point, the controller will run the soft-start function until the fault events are removed. The Under-Voltage Protection (UVP) monitors the voltage at FB pin (VFB) for short-circuit protection when the VFB is less 50% VREF, the controller will shutdown the IC directly.
