目录7.相关产品 产品概述 返回TOP The CXLD64122 integrates a power transistor to provide regulated voltage with maximum output current of 2A. It also incorporates current-limit, thermal shutdown and shutdown control functions into a single chip. The current-limit circuit limits the maximum output current in overload or short-circuit conditions. The on-chip thermal shutdown provides protection against any combination of overload that would create excessive junction temperature. The output voltage of the CXLD64122 tracks the reference voltage on VREF pin. A resistor divider connected to VREF pin is usually used to provide reference voltage to the IC. In addition, an external ceramic capacitorand an open-drain transistor connected toVREF pin provides soft-start and shutdown control.Applying and holding a voltage below 0.35V (typ.) to VREF shuts off the output.产品特点 返回TOP · Fast Transient Response · High Output Accuracy - ±20mV over Load, Output Voltage Offset and Temperature · Adjustable Output Voltage by External Resistors · Current-Limit Protection · On-Chip Thermal Shutdown · Shutdown for Standby or Suspend Mode · Simple SOP-8 and SOP-8 with Thermal Pad Packages · Lead Free Available (RoHS Compliant) 应用范围 返回TOP · VGA Card Power · Chip Set Power 技术规格书(产品PDF) 返回TOP 需要详细的PDF规格书请扫一扫微信联系我们,还可以获得免费样品以及技术支持!
