同步降压型PWM控制器CXSD6274 CXSD6274C固定300kHz开关频率电压模式和同步型PWM控制器来驱动双N通道mos

The CXSD6274 CXSD6274C uses fixed 300kHz switching frequency, voltage mode, and synchronous PWM controller which drives dual N-channel MOSFETs. The device integrates the control, monitoring and protection functions into a single package, provides one controlled power output with under-voltage and over-current protections. The CXSD6274 CXSD6274C provides excellent regulation for output load variation. The internal 0.8V temperature-compensated reference voltage is designed to meet the requirement of low output voltage applications. An built-in digital softstart with fixed soft-start interval prevents the output voltage from overshoot as well as limiting the input current. The CXSD6274 CXSD6274C with excellent protection functions: POR, OCP and UVP. The Power-On-Reset (POR) circuit can monitor VCC supply voltage exceeds its threshold voltage while the controller is running, and a built-in digital soft-start provides output with controlled voltage rise. The Over-Current Protection (OCP) monitors the output current by using the voltage drop across the lower MOSFET’s RDS(ON), comparing with internal VOCP (0.29V), 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 of FB pin for short-circuit protection, when the VFB is less than 50% of VREF (0.4V), the controller will shutdown the IC directly
