The NCP5424DR2G is a DC-DC switching controller designed for use in a variety of applications. It is a part of the innovative Power Management Integrated Circuits (PMIC) family products that offer integrated protection, power supply and voltage regulation. The DC-DC switching controller is specifically designed to support high-efficiency and high-density DC/DC converter designs operating over a wide input voltage and output current range.An on-board active winding controller combines NCP5424 with a transformer to form a multiphase converter. This yields highly efficient, low ripple and low standby power converter designs. Design considerations are simplified with an integrated soft-start, a view mentioned on-time, maximum switch current settings and protection from over-temperature, over-voltage and over-current conditions. This device is only available in the halide-free, green DFN-5 package.The NCP5424 integrates high-performance Pulse Width Modulated (PWM) controllers, a diode-emulated linear regulator and includes a low-voltage detector in order to enable low-power designs. The controller can be set up to support a wide variety of topologies, including buck, boost and dual-mode buck- boost topologies. The PWM controller can be configured to configure the IC’s operating frequency and the edge transition to generate a low ripple at the output with steep slope transition.In terms of features, the NCP5424 offers an Integrated Dual Mode PWM Controller, which allows the user to configure the device to support any of the three topologies supported. It also provides an Internal Soft-Start function, which allows the user to gradually increase the operating voltage without causing inrush current or other issues. The low-Voltage Detector facilitates improved design of the low-voltage protection circuit and ensures the output voltage remains within the valid operating range.In terms of applications, the NCP5424 is suitable for applications that require high efficiency and low-voltage supply, such as automotive applications and mobile phones. The device has also found applications in many power supplies like the ATX, laptop adapters and DC-DC converters. It is designed to operate over an extended temperature range, making it well-suited for a variety of applications.To summarize, the NCP5424DR2G is a highly integrated DC-DC switching controller designed for use in a variety of applications. It includes an innovative PWM controller, integrated soft-start and protection from over-temperature, over-voltage as well as over-current conditions. It is suitable for applications that require high efficiency and low-voltage supply, such as automotive applications and mobile phones. The low-voltage detector feature makes it well-suited for a variety of power supply designs and its extended temperature range makes it well-suited for a variety of applications. The device is available in the halide-free, green DFN-5 package.
