SC4626ZSKTRT is a DC-DC switching regulator from Texas Instruments which can be classified under PMIC (Power Management Integrated Circuit). It belongs to the Voltage Regulators category and within this, to DC DC Switching Regulators. This device offers guidance and support to designers who are looking for a flexible, cost-effective and power-efficient solution for their customer’s application.This device is suitable for a wide range of consumer and industrial applications, such as smartphones, tablets, digital cameras and many other mobile consumer devices. This IC also supports high-power, fast dynamic load steps which can be found in industrial applications, like telecom and automotive applications. Furthermore, this DC-DC switched regulator can handle a wide input voltage range from 4 V to 28 V and provides high efficiency up to 96%.The SC4626ZSKTRT switching regulator can support a wide range of output currents and provides very accurate and stable output voltage. Its adjustable output voltage’s range is from 0.8 V to 15 V with a precision of +- 10 mV at the output. Moreover, this IC features an inrush-current control which helps provide an even, regulated output voltage in spite of large inrush current which can happen when the output is enabled.The main idea for the design of the SC4626ZSKTRT is to minimize the output noise and provide a low output ripple voltage. To achieve this, Texas Instruments implemented a proprietary low-noise technology in the switching regulator. This reduces the external noise by suppressing the switch-node ringing and providing a stable supply voltage to sensitive loads. Additionally, this device allows the designer to customize the output noise performance with the use of external filtering if required.To work, the SC4626ZSKTRT switching regulator is controlled by a feedback loop which ensures that the output voltage is maintained within a precise range. To maintain a precise output voltage, this IC controls an internal error amplifier and a voltage reference. The error amplifier will control the output voltage, by sending a signal to the internal driver switch that is proportional to the output voltage. The master control switch will be opened and closed every switching cycle which will regulate the output voltage by changing the duty cycle of the internal driver switch.To ensure system safety, the SC4626ZSKTRT switching regulator is also equipped with several protection features. This IC offers thermal and overcurrent protection, as well as short and overvoltage protection, which protect against any short circuit and overvoltage situation.The SC4626ZSKTRT DC-DC switching regulator from Texas Instruments offers a compact and cost-effective solution for a wide range of applications. It is easy to use and can be efficiently managed thanks to the integrated feedback loop and protection features. Moreover, this IC provides accurate and stable output voltage and supports high current output, making it a perfect choice for designers looking for a reliable and robust solution.
