The SC1186CSWTRT is designed for use in a variety of different applications and is suitable for use in single-cell lithium-ion and lithium-polymer batteries. It offers two outputs: one linear output with a voltage range of 0.9V19 V, and one switching output with a voltage range of 0.95V–11 V. The application field of the SC1186CSWTRT can be divided into two major groups:

• Portable Applications: The SC1186CSWTRT is well suited for portable applications such as mobile phones, digital cameras and other small electronic devices. It is extremely compact and low-cost, making it suitable for these applications.
• Industrial Applications: The SC1186CSWTRT is widely used in industrial applications such as industrial automation, industrial equipment, data processing equipment, communication systems, and transportation systems. It is designed to provide protection against over-voltages and overloads. This makes it suitable for a wide range of industrial applications.

Working Principle

The SC1186CSWTRT combines a linear regulator and a switching regulator in one package. The linear regulator consists of a P-channel MOSFET switch, a resistor and a capacitor. The linear regulator works by controlling the voltage across the MOSFET switch. The voltage drop across the MOSFET is then compared to a reference voltage, and the current is adjusted accordingly. The switching regulator consists of a high-frequency current-mode PWM (pulse width modulation) control circuit and a high-efficiency synchronous rectifier. The PWM control circuit generates a rectangular pulse that is applied to the input of the synchronous rectifier. The synchronous rectifier then rectifies the alternating current into a DC voltage. The output voltage can then be adjusted by adjusting the duty cycle of the PWM.

The SC1186CSWTRT provides a high-efficiency voltage regulation solution due to its ability to switch between the linear and switching regulators. In low-power applications, the linear regulator is used to regulate the output voltage, while in higher-power applications, the switching regulator is used to reduce losses and provide a higher efficiency. In addition, the SC1186CSWTRT offers protection against over-voltages and short-circuits, ensuring reliable operation of the system.

The SC1186CSWTRT is a unique power management IC that offers both linear and switching regulation solutions. It is suitable for a wide range of applications, from portable devices to industrial automation systems. The device combines a linear regulator and a switching regulator in one package and offers high efficiency and reliable protection against over-voltages and short-circuits.
