   产品概述 返回TOPoMJ嘉泰姆


The CXSD6287 uses fixed 200kHz switching frequency, voltage mode, 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 protection. The CXSD6287 provides excellent regulation for output load variation. The internal 1.2V 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 CXSD6287 with excellent protection functions: POR 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 UnderVoltage Protection (UVP) monitors the voltage of FB pin for short-circuit protection. When the VFB is less than 50% of VREF (0.6V), the controller will shutdown the IC directly.
