S-8338ACIA-T8T1U Application Field and Working Principle
The S-8338ACIA-T8T1U is a DC/DC switching controller that belongs to the class of voltage regulators. It is widely used in modern system designs due to its low current consumption and precise output voltage regulation capability.
The S-8338ACIA-T8T1U is a single-phase synchronous buck controller integrated with a high-side MOSFET, a low-side MOSFET, and a load switch on a monolithic IC. This product supports high-speed and highly precise voltage regulation and also provide powerful EMI reduction, as well as provide standby current of as low as 0.5 µA.
Application Fields
The S-8338ACIA-T8T1U can be used in a wide range applications. It is mainly used in the following fields:
- Automotive systems and communications equipment
- Portable devices and battery-powered products
- Low-power lighting, smart home appliances and more
The S-8338ACIA-T8T1U is also suitable for embedded systems and ICs, computer equipment, and communication routers.
Working Principle
The S-8338ACIA-T8T1U consists of a control circuit and a power switching circuit. It works using a buck-boost topology, which integrates both boost and step-down converter modes. It can support input voltage from 4V to 16V and an output voltage from 0.9V to 15V. The maximum current is limited to 8A (Internally limited to 7A).
The controller comprises of a high-side MOSFET (SW1) and a low-side MOSFET (SW2). The high-side MOSFET works as an active switch with the adjustable duty cycle. After current is provided to the load regulated by the input voltage, it is regulated too be delivered to the output voltage by the DC/DC buck controller. The output voltage of the channel can be controlled by soft start, shutdown, or over-voltage protection,.
Furthermore, S-8338ACIA-T8T1U is capable of providing advanced EMI features, including spread spectrum modulation and a spread frequency modulation. This helps to reduce conducted EMI and improves system EMI performance.
Conclusion
The S-8338ACIA-T8T1U DC/DC buck controller is suitable for a wide range of applications, especially for automotive systems and portable devices that require precise voltage regulation and low current consumption. It features low standby current and high-efficiency, as well as supports advanced EMI features like spread spectrum and spread frequency modulation.
