This device is designed for high-efficiency, low-power applications, allowing for optimum performance and energy savings. SeikoEpson has designed this device for various switching power supplies such as laptop adapters, USB Type-A/C chargers, gaming consoles, and digital signage. Furthermore, this device is suitable for PoE solutions.

The S-8356Q31MC-OYQT2G boasts of a power efficiency of up to 92%, a low quiescent current of 1.05mA (typ.), and supports real time current limit operation. It features a wide frequency range of 500kHz to 2.5MHz and includes a differential amplifier and a hybrid shift register. It has built in overvoltage protection and a dual-mode compensation configuration. The device is capable of operating in both DC-DC buck and boost modes.

The S-8356Q31MC-OYQT2G DC-DC controller provides a variety of features that make it ideal for high-efficiency, low-power applications. It supports current-mode control, including wide bandgap transistors, high-frequency operation, and wide frequency range. The device has an integrated FET gate driver with dual-mode current sense for current limiting. It also has overvoltage protection and thermal protection to protect the device from damage in high-stress environments.

In addition to its efficient operation, the S-8356Q31MC-OYQT2G DC-DC controller features a low-profile design, making it easy to install in crowded environments. It also has a wide input voltage range of 3.5 - 40 VDC. The device supports up to 8 A output current, allowing for higher peak current operation. It is also available in both surface-mount and through-hole packages.

The working principle of the S-8356Q31MC-OYQT2G DC-DC controller is based on pulse width modulation (PWM), a type of analog modulation technique which is used to control the amount of power delivered by the device. The device uses an oscillator to generate a carrier signal which is modulated by the PWM signal. This modulated signal is sent to a switching transistor, which then switches the power supply to the load. The switching transistor will switch the power supply either on or off depending on the PWM signal. The PWM ratio is controlled by the user and can be adjusted to optimize power efficiency.

In short, the S-8356Q31MC-OYQT2G is a high-efficiency, low-power DC-DC controller suitable for high-stress environments, such as gaming consoles and digital signage. The device features wide input voltage range, a wide frequency range, and dual-mode compensation configuration. Furthermore, it supports current-mode control and has a low quiescent current. It is available in both surface-mount and through-hole packages.
