S-8333CBAC-I8T1G: Application Field and Working Principle

S-8333CBAC-I8T1G is a DC-to-DC switching controller. It is used in power management integrated circuit (PMIC), specifically in voltage regulation. It implies guaranteed performance, high efficiency, and minimized power loss.

The application field of S-8333CBAC-I8T1G covers various devices like mobile phones, tablets, TVs, and home appliances that have built-in power management applications. It is especially suitable for power optimization solutions for Intel’s I8T1G architecture.

Working Principle

S-8333CBAC-I8T1G is based on the principle of switching controllers. It is equipped with voltage regulation features and the ability to adjust its output voltage in response to the load condition. It ensures a stable and reliable output voltage.

It has two power stages that provide power to the output: a high-side switch and a low-side switch. Both switches are controlled by the control circuit. The power stages are responsible for converting the input voltage to the desired output voltage. The control circuit action depends on the current load and the output voltage condition.

The control circuit is the brains of the system. It is enabled by an overcurrent protection circuit, which switches off the system when the current exceeds the safe limit. It also contains an error amplifier, which set the desired output voltage and monitors any changes in the voltage. Furthermore, a comparator compares the actual and requested voltage, and feeds the difference to the PWM generator. Depending on this difference, the PWM generator resets the current via the power stages and adjusts the output voltage.

S-8333CBAC-I8T1G provides various control modes. These include pulse-width modulated (PWM) mode, pulse-frequency modulated (PFM) mode, skip PWM and skip PFM modes. These modes are used to adjust the output voltage by delay, low and high current limiters. The on-off ratio of the delay limiter limits voltage redundancy and helps reduce power consumption.
